⚠️ Critical Replacement Notes

1. Motor load AC-3 (90kW): No impact, remplacement direct
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. Stratégie pièces de rechange: New projects specify AX185 only; A185 only for emergency maintenance with existing stock
6. This list applies to Axxx-30-11-80 (3-pôle, built-in 1NO+1NC auxiliary, Bobine AC220V, discontinued old A series); suffixe -80 = 220VAC coil
7. AX replacement: AXxxx-30-11-80, official direct upgrade for A series
8. Comparison basis: AC-3 @400V motor duty; 220Bobine V, built-in 1NO+1NC for Schneider LC1D and Siemens 3RT5/3RT6
9. Note: Only electrical equivalent rating, not mechanically interchangeable; trous de montage, busbar and accessories are not compatible; HS code unified 85364900
10. ABB Old A Series Contactor List (Discontinué, 30-11-80, 220ACC)

Remarque: 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, 220Bobine V, 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. Rail DIN, trous de montage, terminal spacing and thermal relay interfaces are incompatible
6. Coil code rules (common for A & HACHE):

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

84: AC110~120V

83: AC48V

85: AC380~400V

4. If you need other coil voltages (par exemple. -84 for 110V), I can export a full list with -84 numéros de pièces
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, tenue aux courts-circuits plus élevée, rated up to 1000V insulation; suitable for heavy duty, AC-4 frequent reversing, high voltage and high-reliability legacy equipment. Drawbacks: abandonné, 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, CVC, 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. Réparation & overhaul of legacy original panels (old ABB packaged cabinets, large air compressors, extrudeuses, papier & metallurgy lines; drawing specification locked to A series, no busbar / cabinet modification allowed)
2. AC-4 frequent reversing, jogging, heavy shock loads: palans, grues, concasseurs, tables à rouleaux, 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

Nouveaux projets, mass OEM, budget serré, 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. Nouveaux projets, OEM batch equipment, standard control cabinets: Lignes de convoyage, machines d'emballage, general fans & pompes, HVAC chillers. Good versatility, stable supply and favorable bulk pricing.
2. Ascenseur, crane auxiliary circuits, door motors, frein & star-point control: Mature industry adoption, contacts auxiliaires abondants, verrouillages mécaniques, timer blocks and mirror NC contacts.
3. Solutions requiring complex accessory combinations: Verrouillage mécanique, pneumatic timer, suppresseur de surtension, 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, ASC, 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)

Tableau de comparaison

Guide de sélection rapide

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 (même empreinte, 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.
