2CSS200910R0005 ABB S2C-OVP1 Overvoltage Release 230 V AC 275 V Maximum Tripping Voltage

Why Choose the ABB S2C-OVP1 Overvoltage Release?

The ABB S2C-OVP1 is an overvoltage release accessory designed to monitor the voltage between phase and neutral and initiate tripping of an associated compatible circuit protection device when an excessive voltage condition occurs. Supplied under ABB order code 2CSS200910R0005, it provides automatic overvoltage response for ABB modular protection systems.

As part of ABB’s range of MCB accessories, the S2C-OVP1 has a rated voltage of 230 V AC at 50 Hz. Its maximum non-tripping voltage is 253 V AC, while its maximum tripping voltage is 275 V AC, allowing the accessory to detect potentially damaging voltage rises and operate the associated protective device.

The S2C-OVP1 is suitable for compatible ABB modular devices including S200 and S300P miniature circuit breakers, F200 RCCBs and selected DS-series RCBOs. Its compact modular format measures approximately 85 × 18 × 68 mm and is designed for integration alongside compatible protection devices in electrical distribution boards and control panels.

Automatic Overvoltage Monitoring for Circuit Protection

The ABB S2C-OVP1 continuously monitors voltage between the neutral and phase conductors. When an overvoltage reaches the specified threshold, the accessory causes its associated compatible MCB, RCCB or RCBO to trip, helping disconnect the downstream circuit from the abnormal supply condition.

The S2C-OVP1 can be integrated with compatible ABB modular protection products including S200, S300P, F200, DS201, DS202C, DS203NC and other supported ranges. SN201 and DS203NC installations use the appropriate SN201-IH interface arrangement when connecting the overvoltage release.
