Why Choose the ABB GHV2501910R0001 RD7/250 Surge Suppressor?
The ABB GHV2501910R0001, also known as the RD7/250, is a compact diode surge suppressor for contactor coils designed to reduce transient overvoltages generated when DC-operated contactors are switched. It provides effective suppression of the maximum overvoltage peak and helps limit or eliminate high-frequency pre-damping oscillations that can affect sensitive industrial control equipment.
Designed for a broad 24–250 V DC control voltage range, the RD7/250 provides a versatile suppression solution for multiple DC contactor coil voltages. Its diode-based suppression circuit helps protect PLC outputs, electronic control modules and other connected equipment from the inductive voltage spikes produced when a contactor coil is de-energised.
The GHV2501910R0001 is designed for compatible ABB B6 and B7 DC-operated mini contactors and features screw terminals for straightforward electrical connection. With compact dimensions of approximately 21 × 11.5 × 12 mm and a net weight of approximately 0.005 kg, it provides effective surge suppression while adding minimal size to the contactor assembly.

Reliable Surge Suppression for DC Contactor Coils
When a DC contactor coil is de-energised, the collapsing magnetic field can generate a substantial inductive voltage spike. The ABB RD7/250 uses diode suppression to reduce this maximum overvoltage peak and limit high-frequency voltage oscillations, helping prevent excessive electrical stress on connected control components.
This type of suppression is particularly valuable where mini contactors are operated by PLCs or electronic control outputs. Installing the GHV2501910R0001 on a compatible ABB B6 or B7 mini contactor helps protect sensitive electronics, reduce switching interference and support reliable operation of industrial automation and machine control systems.
Typical Applications
- ABB B6 and B7 DC-operated mini contactors.
- PLC-controlled contactor circuits.
- Industrial motor control panels.
- Machine automation systems.
- Industrial control cabinets.
- Material handling and conveyor systems.
- Packaging and production machinery.
- OEM electrical and automation equipment.
