Why Choose the ABB GHV2501903R0002 RV-BC6/250 Surge Suppressor?
The ABB GHV2501903R0002, also known as the RV-BC6/250, is a compact varistor surge suppressor designed to protect DC-operated mini contactor control circuits against transient overvoltages generated when the contactor coil is switched. It is an ABB contactor accessory developed for compatible B-series mini contactors and provides effective suppression of potentially damaging switching transients.
The RV-BC6/250 is designed for 50–250 V DC control circuits and uses varistor technology to limit transient voltage across the contactor coil. By suppressing these voltage peaks, the device helps protect PLC outputs, electronic control equipment and other sensitive components while reducing electrical interference within industrial automation systems.
Designed for compatible ABB B6 and B7 mini contactors, the GHV2501903R0002 uses a screw-terminal connection and compact accessory format for straightforward integration into industrial control panels. Its 690 V rated insulation voltage and purpose-designed construction make it a practical solution for machine control, automation and electrical switching applications using DC-operated mini contactors.

Reliable Surge Suppression for Contactor Control Circuits
When a DC contactor coil is de-energised, the collapsing magnetic field can generate a substantial transient voltage. A varistor surge suppressor such as the ABB RV-BC6/250 limits this transient by providing voltage-dependent suppression across the coil, helping prevent excessive voltage from reaching connected control electronics.
Effective coil suppression is particularly valuable in automated machinery where contactors are controlled by PLCs, relays or electronic output modules. Installing the GHV2501903R0002 on a compatible ABB mini contactor helps reduce electrical interference and transient stress while supporting reliable switching performance in industrial control systems.
Typical Applications
- ABB B6 and B7 mini contactor installations.
- Industrial motor control panels.
- PLC-controlled contactor circuits.
- Machine automation systems.
- Industrial control cabinets.
- Material handling and conveyor systems.
- Packaging and production machinery.
