ABB RV5/50 1SBN050010R1000 Surge Suppressor

Configured for overvoltage suppression in AC-operated contactor control circuits, the ABB 1SBN050010R1000 (RV5/50 Surge Suppressor) provides direct limitation of transient voltage peaks generated during contactor coil switching. The unit utilizes varistor-based suppression technology to reduce high-frequency switching disturbances and protect associated control components.

Hardware Specifications

Surge Voltage Protection Characteristics

The RV5/50 is designed to reduce maximum overvoltage peaks generated during control coil de-energization. The varistor network limits transient voltage amplitudes and reduces high-frequency disturbances that can affect nearby control circuits, relays, and electronic equipment.

Contactor Coil Protection

The suppressor is intended for installation on compatible ABB contactors including AS09, AS12, AS16, ASL09, ASL12, ASL16, NS22E, NS31E, NS40E, and NS44E series devices. By controlling switching transients, the module helps reduce electrical stress on connected control components.

Frequently Asked Questions

Q: What control voltage range is supported?
A: The RV5/50 is designed for control circuit voltages from 24 V to 50 V in AC or DC applications.

Q: What suppression technology is used?
A: The module utilizes a varistor-based surge suppression circuit.

Q: Can the suppressor be installed on compatible ABB contactors directly?
A: Yes. The device is designed as an accessory for designated ABB contactor families.

Field Installation Guidelines

• Verify compatibility with the target contactor model before installation.

• Isolate control circuit power before mounting the suppressor.

• Ensure correct connection to the contactor coil terminals.

• Inspect all wiring and terminal connections before energization.

• Operate the device within the specified temperature range and voltage ratings.
