2CSS200993R0005 ABB S2C-OVP2 Overvoltage Release 230 V AC 290 V Maximum Tripping Voltage

Why Choose the ABB S2C-OVP2 Overvoltage Release?

The ABB S2C-OVP2 is a compact overvoltage release 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 2CSS200993R0005, it provides automatic overvoltage response within ABB System pro M compact installations.

The S2C-OVP2 has a rated voltage of 230 V AC at 50 Hz, with a maximum non-tripping voltage of 253 V AC and maximum tripping voltage of 290 V AC. When the monitored voltage reaches the overvoltage threshold, the accessory causes the associated compatible MCB, RCCB or RCBO to trip.

Designed for integration with ABB modular protection equipment, the S2C-OVP2 is suitable for product ranges including S200, S300P, SN201, F200, DS201, DS202C and DS203NC. Its compact modular construction makes it suitable for electrical distribution boards and control panels where automatic protection against excessive supply voltage is required.

Automatic Overvoltage Monitoring for Electrical Circuits

The ABB S2C-OVP2 monitors voltage between the phase and neutral conductors. If an overvoltage reaches the specified threshold, the release operates the associated compatible circuit protection device, disconnecting the downstream circuit and helping protect electrical equipment from sustained excessive supply voltage.

The S2C-OVP2 can be used with compatible ABB modular devices including S200, S300P and SN201 miniature circuit breakers, F200 residual current devices, DS201, DS202C and DS203NC RCBOs, as well as other supported ABB modular protection products.

Typical Applications

• Residential electrical distribution boards.
• Commercial electrical installations.
• Industrial distribution and control panels.
• ABB miniature circuit breaker installations.
• ABB residual current protection systems.
• Circuits requiring automatic response to excessive supply voltage.
• OEM electrical equipment and modular switchgear assemblies.
