Why Choose the ABB S802S-UCK1 High Performance MCB?
The ABB S802S-UCK1 is a high-performance two-pole miniature circuit breaker (MCB) designed for reliable protection of DC cables and circuits against overload and short-circuit currents. As part of the ABB S800S-UC high-performance MCB range, it is engineered for demanding industrial applications requiring high fault-current interruption capability and dependable circuit protection.
Featuring a 1 A rated current, K tripping characteristic and an ultimate short-circuit breaking capacity of 50 kA, the S802S-UCK1 combines thermal overload protection with electromagnetic short-circuit protection. Its K characteristic makes it suitable for appropriate circuits where higher starting or inrush currents may occur, while ABB's rapid arc-extinction technology supports safe interruption of high fault currents.
The S802S-UCK1 is rated for 500 V DC in its two-pole configuration and complies with IEC/EN 60947-2. With ABB order code 2CCF030034R0001, its industrial design, cage-terminal connection system and broad S800 accessory compatibility make it a versatile protection solution for DC distribution, machinery and automation installations.
