ABB Contactor Varistor for use with BC6, VBC7, KC6, VBC6A, VBC7A, VBC6, TKC6, TBC7, BC7

This contactor varistor protects control circuits from transient voltage spikes in AC and DC Coil systems. Designed as an accessory for a range of contactor families, it provides surge suppression for Coil voltages between 12-60V AC/DC and integrates into typical industrial control and automation assemblies. The component meets RoHS restrictions and is intended for retrofit or replacement use with compatible contactor units.

• 12-60VAC/DC range provides broad Coil voltage protection
• Varistor element suppresses transient overvoltages to protect Coils
• Compatible with multiple contactor types simplifies stocking
• Component meets RoHS standards for restricted-substance compliance

• Suitable for use with BC6 contactor Coils in automation panels
• Used with VBC7 contactors for surge suppression on Coil circuits
• Ideal for replacement in KC6 and TKC6 assemblies during maintenance
• Used for retrofit protection on VBC6A and VBC7A Coil modules
• Suitable for TBC7 contactors where varistor accessories are required

It is fitted as an accessory across the Coil terminals to clamp transient voltages during switching events.

It operates across a range of nominal Coil supplies from 12V up to 60V on both AC and DC systems.

Yes, it is designed to be compatible with multiple contactor types so it can serve as a replacement part in varied inventories.

The device is compliant with RoHS limits on hazardous substances.
