Comparison: ABB A185-30-11-80 VS AX185-30-11-80

Suffix -80 same definition: AC220~230V 50Hz / AC230~240V 60Hz; Mounting hole position, main terminal layout and auxiliary contact definition are fully compatible, direct on-site replacement

⚠️ Critical Replacement Notes

1. Motor load AC-3 (90kW): No impact, direct replacement
2. Long-term AC-1 resistive load near 250A: Evaluate carefully; A185 Ith=275A provides larger margin
3. Circuit voltage >690V: AX is not suitable, cannot replace
4. Extra 2.3mm depth: Check clearance if contactor is fitted tight against cable trunking or door plate
5. Spare parts strategy: New projects specify AX185 only; A185 only for emergency maintenance with existing stock
6. This list applies to Axxx-30-11-80 (3-pole, built-in 1NO+1NC auxiliary, AC220V coil, discontinued old A series); suffix -80 = 220VAC coil
7. AX replacement: AXxxx-30-11-80, official direct upgrade for A series
8. Comparison basis: AC-3 @400V motor duty; 220V coil, built-in 1NO+1NC for Schneider LC1D and Siemens 3RT5/3RT6
9. Note: Only electrical equivalent rating, not mechanically interchangeable; mounting holes, busbar and accessories are not compatible; HS code unified 85364900
10. ABB Old A Series Contactor List (Discontinued, 30-11-80, 220VAC)

Remark: A series also includes A370, A400, A500 larger frames, rarely used for general projects. A series is different from AF series (AF = wide-voltage coil type, not included here)

2. Cross-Brand Equivalent Rating Table (AC-3 400V, 220V coil, built-in 1NO+1NC)

3. Important Replacement Reminders
4. A → AX is the only drop-in compatible upgrade: Same mounting pitch, terminal layout and auxiliary contact logic; no busbar modification required
5. Schneider LC1D and Siemens 3RT5: Only electrical equivalent, not mechanically interchangeable. DIN rail, mounting holes, terminal spacing and thermal relay interfaces are incompatible
6. Coil code rules (common for A & AX):

80: AC220~230V 50Hz / 230~240V 60Hz

84: AC110~120V

83: AC48V

85: AC380~400V

4. If you need other coil voltages (e.g. -84 for 110V), I can export a full list with -84 part numbers
5. Thermal relays: TA series is ABB dedicated. Schneider LRD and Siemens 3RU cannot clip directly onto A / AX contactors

Old ABB A series: Larger contact margin, higher short-circuit withstand, rated up to 1000V insulation; suitable for heavy duty, AC-4 frequent reversing, high voltage and high-reliability legacy equipment. Drawbacks: discontinued, scarce stock, higher coil noise, shrinking accessory ecosystem.

Schneider LC1D (TeSys D): Rich accessory portfolio, wide coil options, stable stock, cost competitive. Optimized for standard AC-3 motor duty, OEM mass production, HVAC, elevators and standardized automation projects. Lower overload margin for extreme heavy shock loads.

Application Scenario Difference between Old ABB A series and Schneider LC1D

✅ Preferred applications for Old ABB A series

1. Repair & overhaul of legacy original panels (old ABB packaged cabinets, large air compressors, extruders, paper & metallurgy lines; drawing specification locked to A series, no busbar / cabinet modification allowed)
2. AC-4 frequent reversing, jogging, heavy shock loads: hoists, cranes, crushers, roller tables, extruder main motors. Thicker silver contacts, higher thermal margin and superior 1s short-time withstand against current surges.
3. 690V motor circuits, high-power fans/pumps, high AC-1 resistive loads: Ui=1000V, higher Ith rating, suitable for continuous full resistive loading such as heating elements, furnace banks and bus transfer.
4. Process-critical equipment requiring high short-circuit withstand and Type 2 coordination: Production lines where contact welding is unacceptable.
5. Integrated ABB motor control packages: Matched with ABB MCB, Tmax MCCB and TA thermal relays for factory-tested protection coordination.

❌ Not recommended for A series

New projects, mass OEM, tight budget, heavy custom accessory requirements, stable lead time demand. A series is discontinued with rising premium and shrinking stock.

Weakness: Audible coil noise relatively high; fewer accessory choices vs LC1D; large frame stock volatile.

✅ Preferred applications for Schneider LC1D (TeSys D)

1. New projects, OEM batch equipment, standard control cabinets: Conveyor lines, packaging machinery, general fans & pumps, HVAC chillers. Good versatility, stable supply and favorable bulk pricing.
2. Elevator, crane auxiliary circuits, door motors, brake & star-point control: Mature industry adoption, abundant auxiliary contacts, mechanical interlocks, timer blocks and mirror NC contacts.
3. Solutions requiring complex accessory combinations: Mechanical interlock, pneumatic timer, surge suppressor, extra auxiliary blocks, reversing contactor sets and star-delta modules. TeSys D has the broadest accessory range among the three brands.
4. Wide coil selection demand: AC24V, DC24V, DC110V, wide voltage coils, ideal for direct PLC DC output driving.
5. Export equipment with multi-certification requirements: UL, CSA, marine approvals widely available.
6. Standard AC-3 duty, operation frequency ≤300 times/hour, without frequent jogging or heavy surges for general motors.

❌ Not recommended for LC1D

Continuous operation above 690V

High-frequency AC-4 heavy duty with repeated current surges (lower contact margin than old A series at same rating)

Direct replacement into legacy ABB cabinets (requires rework of mounting, busbars and thermal relay interface)

Comparison Table

Quick Selection Guide

Old ABB cabinet repair, crane/crusher frequent reversing, 690V motor, no busbar change → Prefer A stock or AX

New cabinet, mass OEM, elevator/HVAC, reversing/star-delta, budget focus, stable supply → LC1D

Heavy shock loads and long-term stocking: Avoid A on new projects; choose AX. LC1D if budget limited and margin acceptable.

Important distinction: AX is the compatible upgrade for A (same footprint, conservative performance de-rating). LC1D is only electrically equivalent, not mechanically interchangeable.

I can provide AC-4 derating margin recommendation for A, AX and LC1D if you require.
