- Description
Rated for 24-36 V AC/DC control circuits, the ABB 2CCS800900R0241 S800-UVR36 is an undervoltage release accessory that automatically opens a compatible S800 high performance circuit breaker if its low-voltage control supply collapses or is deliberately removed. It suits panels powered from 24 V DC PLC supplies or small control transformers that need a fail-safe no-volt trip path.

Selection Notes
The 2CCS800900R0241 is an undervoltage release rated for 24-36 V AC/DC control circuits, matching 24 V DC PLC supplies and small control transformers used in low-voltage switchgear panels. Its automatic trip on loss of control voltage provides a fail-safe no-volt path that operates independently of the breaker's own overcurrent protection, which matters where safety interlocks must open the main breaker on power loss. Panels running a higher control voltage need the UVR version sized for that voltage; this 24-36 V unit will not hold in correctly on a 110 V or 230 V circuit.
