Domestic Equivalent List for LC1D150 (AC-3 @400V, 150 UN, 75 kW, 3P)

Nota sulla selezione: CJX2-150 has the closest outline, mounting dimension and accessory system to LC1D150; coil voltage available in AC110 V to perfectly match your original F7 (AC110 V) circuito; all with CCC certification, GB/T14048.4 / IEC60947-4-1

Livello 1 Marche (Widely used in engineering, prestazioni affidabili)

1. CHINT NC2-150 / CJX2-150

NC2: CHINT main heavy-current series; CJX2-150 adopts TeSys D imitation structure, mounting hole spacing close to LC1D150

AC-3 @400 V: 150 UN, 75 kW; coil voltages AC110 V, 220 V, 380 V opzionale

Ausiliario: Nessun contatto ausiliario integrato; F4 auxiliary blocks and pneumatic timers can be added, same operation as Schneider Serie LAD

Matching thermal relay: NR2-200 (covers 150 UN)

2. DELIXI CJX2-150

Largest market inventory, convenient for replacement; same structure as TeSys D

AC-3 150 UN / 75 kW; terminali a vite; compatible with F4 auxiliary blocks, pneumatic timers and mechanical interlocks

3. TENGEN CJX2-150

Stessa specifica, consistent accessory system; widely adopted by panel builders for LC1D replacement

Old model CJT1-150: outdated structure, large size, not recommended for new project replacement

4. People Electric CJX2-150

Consistent rating, AC-3 150 UN, 75 kW; complete coil voltage options, also used for export projects

Livello 2 / Direct Replacement Specialized Models

BOWO BWDC1-150F: Specially designed to match LC1D series, nearly identical dimensions, AC-3 150 UN, AC110 V coil optional, clearly marked silver contact configuration, suitable for bulk replacement

Other Wenzhou manufacturers: CJX2-150 (Jubang, Nader NDC2-150, ecc.). Nader is high-end domestic brand with longer electrical life and better surge resistance, priced higher than CHINT and DELIXI

⚠️ Critical Selection Notes

1. CJX2-150 (115~170 A frame) has NO built-in auxiliary contacts!

LC1D150 comes with factory 1NO+1NC; domestic CJX2-150 has no onboard auxiliary contacts. F4-11 (1NA+1NC) deve essere ordinato separatamente, otherwise control circuit feedback signal will be missing — this is the most common pitfall during replacement.

2. Dimensions are NOT 100% identical

CJX2-150 shares similar overall outline, with minor deviations on mounting pitch and busbar width. For direct in-cabinet drop-in replacement, BWDC1-150F is preferred, or verify cutout dimensions in advance.

3. CJT1-150 is not recommended for direct replacement

Old-style design, bulky, incompatible with F4 auxiliary blocks. Only for maintenance of legacy equipment of the same model, not for LC1D substitution.

4. Coil designation example: CJX2-150 AC110 V corresponds to LC1D150F7 (AC110 V 50/60 Hz)

✅ Quick Recommendation

Standard panel build, sensibile ai costi: DELIXI CJX2-150 + F4-11 auxiliary block

Prioritize form-fit interchange with Schneider: BOWO BWDC1-150F AC110 V

High-end domestic, lunga durata: Nader NDC2-150

✅ Advantages of Schneider TeSys D (LC1D)

1. Convenient wiring and assembly

Auxiliary contacts mounted on top; LADN auxiliary blocks, timers and surge modules are easy to fit. Many frame sizes come with built-in 1NO+1NC (including LC1D150), no extra auxiliary block required. Reversing and star-delta assemblies are simple, widely adopted by panel shops.

2. Strong supply chain, stock availability and mature replacement ecosystem

Large domestic stock volume; mature CJX2 domestic substitute system for maintenance and spare parts. Dominant in HVAC, pompa, general motor control cabinets and building distribution.

3. Tolerant coil voltage margin

Better tolerance for fluctuating grid voltage and voltage drop on site; wide-voltage coil options abundant.

4. Intuitive model naming: LC1Dxx easy to identify, rich Chinese datasheets and selection tools.

Limitazioni:

No native integration advantage with Siemens PLC / TIA Portal ecosystem;

Higher cost for high-current frames; legacy TeSys D models gradually phased out (per esempio. your LC1D150F7).

✅ Advantages of Siemens SIRIUS 3RT

1. Robust German design for harsh operating conditions

Solid construction, proven performance in heavy industry, minerario, rail and frequent AC-4 inching applications; conservative overcurrent and short-time withstand design for impact loads.

2. Best compatibility with Siemens PLC / TIA full system

3RT2 paired with 3RU thermal relays and 3RV motor protectors under unified SIRIUS platform. Native EPLAN macros and TIA device library support, simplified BOM and documentation for standardized machines and panels.

3. Flexible modular expansion

Side-mounted auxiliary contacts allowing stacking of multiple feedback and diagnostic modules, ideal for systems requiring numerous feedback signals and safety circuits.

Limitazioni:

Side-mounted auxiliary contacts are awkward for wiring when cabinet space is tight; most frames have no built-in auxiliary contacts and require separate ordering;

Domestic substitute compatibility is less mature than Schneider CJX2 ecosystem;

Same rating usually at higher price; longer lead time occasionally for spare parts.

📌 Quick Selection Guide (150 Una cornice)

Choose Schneider LC1D: Fan / pompa / HVAC, municipal fire pump, replacement of existing LC1D, unstable grid voltage, easy future domestic substitution

Choose Siemens 3RT: Full Siemens automation system, servizio pesante / frequent AC-4 inching, minerario / metallurgia / crane, customer-specified German brand standard, multiple auxiliary feedback and diagnostic points

Quality baseline: Both comply with IEC60947-4-1 and CCC. Under normal fan/pump AC-3 non-frequent duty cycle, failure rate difference is minimal. Most on-site issues come from mismatched accessories rather than the contactor itself: Schneider LRD and Siemens 3RU thermal relays cannot be intermixed, different latching structure and trip curves.

📌 Suggestion for Your Current Project

Your reference: LC1D150F7 (AC110 V, 150 UN, 75 motore da kW)

If PLC inside cabinet is Siemens and full system standardization is required: select 3RT2055-1AF00 (AC110 V) with matching 3RU2 thermal relay

If only direct replacement and maintainability with budget control: prefer new Schneider TeSys Deca variant or domestic CJX2-150

Direct drop-in interchange between the two brands is NOT feasible: different mounting holes, thermal relay latch geometry and auxiliary contact layout.

1. Application Scenarios for Schneider TeSys (LC1D/Deca) Contattori

Posizionamento centrale: Scopo generale, costruzione HVAC, municipal, standard panel, maintenance-friendly

1. HVAC air conditioning, chiller units, air-cooled heat pumps

4. Macchinari generali, standard conveyor lines, macchine per l'imballaggio, woodworking machines

Normal AC-3 on/off duty (low inching frequency); high BOM and wiring efficiency for mass standard panel production.

5. Retrofit and legacy equipment replacement

Direct replacement of failed original LC1D contactors; renovation projects without full automation platform migration and moderate budget.

6. New energy auxiliary systems, cooling fans for energy storage systems

❌ Not preferred: Heavy impact loads, high-frequency AC-4 inching, full Siemens TIA automation solution, transito ferroviario, mining and metallurgy.

2. Application Scenarios for Siemens SIRIUS 3RT Contactors

Posizionamento centrale: Industria pesante, alta affidabilità, funzionamento frequente, Siemens automation platform, ambienti difficili

1. Metallurgia, minerario, aggregate, cemento, chemical heavy-duty machinery

High inrush current, dusty and vibrating environment; AC-4 inching and frequent reversing (roller tables, winches, frantoi) with conservative contact withstand margin.

2. Macchine utensili, automotive assembly lines, robotic workcells

Full stack of PLC, VFD and safety relays from Siemens (Portale TIA). Standardized EPLAN drawings and device diagnostics for OEM and export machines.

4. Power auxiliary systems, generator control panels

Widely specified by power industry designers for low-voltage auxiliary assemblies.

5. High-end custom machinery, European export equipment

German-standard projects with customer mandatory Siemens brand requirement.

❌ Not preferred: Direct replacement of legacy Schneider contactors, budget ristretto, expectation of easy domestic substitute, limited cabinet space for auxiliary wiring.

3. One-sentence Selection Rule (150 UN /75 kW frame)

Schneider: Fan/pump/HVAC, municipal fire pump, legacy LC1D replacement, easy domestic spare support, unstable grid voltage

Siemens: Full Siemens PLC solution, frequent AC-4 inching, mining/metallurgy/crane, customer-specified German system

4. Additional Pitfall Reminders
5. Thermal relays cannot cross brands: Schneider LRD and Siemens 3RU have incompatible clip mounting and different trip characteristic curves.
6. Cross-brand substitution is not impossible, but accessories and mounting layout differ. New projects are recommended to maintain single-brand consistency.
7. Both meet CCC and IEC60947-4-1. Failure rate difference is negligible for standard fan/pump AC-3 non-frequent operation.
