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

선택 참고 사항: 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) 회로; all with CCC certification, GB/T14048.4 / IEC60947-4-1

Tier 1 브랜드 (Widely used in engineering, 안정적인 성능)

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 에이, 75 kW; coil voltages AC110 V, 220 다섯, 380 V 선택 사항

보조자: 내장된 보조 접점 없음; F4 auxiliary blocks and pneumatic timers can be added, same operation as 슈나이더 LAD 시리즈

일치하는 열 릴레이: NR2-200 (covers 150 에이)

2. DELIXI CJX2-150

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

AC-3 150 에이 / 75 kW; 나사 터미널; compatible with F4 auxiliary blocks, pneumatic timers and mechanical interlocks

Tier 2 / Direct Replacement Specialized Models

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

Other Wenzhou manufacturers: CJX2-150 (Jubang, Nader NDC2-150, 등.). 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 (1아니요+1NC) 별도로 주문해야 합니다, otherwise control circuit feedback signal will be missing — this is the most common pitfall during replacement.

2. Dimensions are NOT 100% 동일한

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 헤르츠)

✅ Quick Recommendation

Standard panel build, 비용에 민감한: DELIXI CJX2-150 + F4-11 auxiliary block

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

High-end domestic, 긴 서비스 수명: 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, 펌프, 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.

제한사항:

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

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

✅ Advantages of Siemens SIRIUS 3RT

1. Robust German design for harsh operating conditions

Solid construction, proven performance in heavy industry, 채광, 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.

제한사항:

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 프레임)

Choose Schneider LC1D: 팬 / 펌프 / 공조, municipal fire pump, replacement of existing LC1D, unstable grid voltage, easy future domestic substitution

Choose Siemens 3RT: Full Siemens automation system, 헤비 듀티 / frequent AC-4 inching, 채광 / 야금 / 기중기, 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 에이, 75 kW 모터)

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: 다양한 장착 구멍, thermal relay latch geometry and auxiliary contact layout.

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, tight budget, expectation of easy domestic substitute, limited cabinet space for auxiliary wiring.

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

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

지멘스: 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.
