ABB Mini Contactors & Contactor Relays

Power contactors, reversing assemblies and control relays

ABB’s mini-contactor documentation distinguishes B/BC contactors from VB/VBC compact reversing contactors and K/KC mini contactor relays. The power-contact and control-contact duties are different; the entire list should not be described as auxiliary-only contactors.

B and BC references include different coil-supply versions. VB and VBC are compact reversing configurations with specific wiring and accessory arrangements. K and KC are contactor relays for control-circuit switching. Confirm the full model rather than assuming one coil supply, terminal type or contact configuration applies to all families.

Selection conditions

• Identify motor/power switching, reversing duty or auxiliary/control switching.
• Specify load voltage, current and utilization category. Motor AC-3 ratings and control-circuit AC-15/DC-13 ratings describe different duties.
• Confirm coil voltage, AC/DC supply, frequency and coil consumption for the complete code.
• Specify main and auxiliary contact arrangement, mounting and screw, flat-pin or solder connection requirements.
• For a reversing assembly, check the actual wiring, interlocking and protection coordination.
• Confirm accessory fit individually. ABB’s catalogue restricts accessory combinations and fitting positions; do not assume every CA6/CAF6 accessory fits every reversing or low-consumption version.

Catalogue and historical reference boundaries

The original table and model examples remain unchanged. ABB’s mini-contactor catalogue provides family and version-specific technical information; regional approvals and legacy parameters should be confirmed for the full code. No plug-in, replacement or universal compatibility claim is made.

Information for quotation

Send the full model, ABB code, quantity and destination country. Include the load/application, main and control voltages, required contacts, connection/mounting and accessories. For existing equipment, add nameplate and wiring photos. Product status and current availability should be confirmed before ordering.
