2CCS861002R1825 ABB S801S-UCB100-R High Performance MCB 50kA 1P Type B 100A

Why Choose the ABB S801S-UCB100-R High Performance MCB?

The ABB S801S-UCB100-R is a high-performance single-pole miniature circuit breaker (MCB) designed to provide reliable overload and short-circuit protection in demanding electrical installations. Part of the ABB S800S high-performance circuit breaker range, this model combines a 100 A rated current, Type B tripping characteristic and 50 kA breaking-capacity class.

The S801S-UCB100-R combines thermal overload protection with rapid electromagnetic short-circuit tripping. Its Type B characteristic is suited to circuits with relatively low normal starting or inrush currents, providing sensitive fault protection while the current-limiting operating principle helps reduce electrical and thermal stresses during severe fault conditions.

With its 1-pole configuration, robust S800S construction and high fault-current capability, the S801S-UCB100-R is well suited to demanding distribution, feeder and equipment circuits. ABB order code 2CCS861002R1825 identifies this specific 100 A Type B model.

Reliable High-Performance Circuit Protection

Miniature circuit breakers such as the ABB S801S-UCB100-R automatically disconnect a protected circuit when excessive current results from an overload or short circuit. The thermal trip responds to sustained overload conditions, while the electromagnetic trip provides rapid interruption during severe short-circuit faults, helping protect conductors and connected electrical equipment.

The Type B characteristic makes the S801S-UCB100-R suitable for appropriate circuits where normal starting currents are relatively low and a sensitive magnetic trip response is required. Combined with the S800S platform's high breaking-capacity class and current-limiting operation, it provides dependable protection for demanding distribution, feeder and equipment circuits.
