Why Choose the ABB RV5/133 Surge Suppressor?
The ABB RV5/133, order code 1SBN050010R1001, is a compact varistor surge suppressor designed to protect contactor control circuits from transient overvoltages. It limits voltage peaks generated when an energised contactor coil is switched off, helping protect nearby electronic devices, insulation and sensitive control components.
Switching an inductive contactor coil can release stored electromagnetic energy as a high-voltage surge. The RV5/133 reduces the maximum overvoltage peak and attenuates high-frequency pre-damping oscillations, supporting more reliable operation in industrial automation and motor-control installations.
Designed for conventional AC- or DC-operated contactors with a rated control circuit voltage of 50–133 V AC/DC, the RV5/133 provides a straightforward method of coil surge suppression. Its compact housing enables integration with compatible ABB contactors without occupying significant control-panel space.

Reliable Suppression for Contactor Control Circuits
Contactor coils are inductive loads that store electromagnetic energy while energised. When the coil circuit opens, this energy can produce a steep transient voltage capable of disrupting electronic controls, accelerating insulation wear or damaging sensitive circuit components.
The ABB RV5/133 uses a varistor connected across the contactor coil to restrict the resulting voltage peak. Its ability to operate with both AC and DC control supplies makes it a versatile suppression accessory for industrial automation, motor control and power-switching equipment.
Typical Applications
- Industrial contactor coil protection.
- Motor-control centres and starter panels.
- PLC-controlled contactor circuits.
- Industrial machinery and automation systems.
- Power distribution and load-switching panels.
- Control circuits containing surge-sensitive electronic equipment.
