Why Choose the ABB S802S-B4 High Performance MCB?
The ABB S802S-B4 is a high-performance two-pole miniature circuit breaker (MCB) designed to provide dependable overload and short-circuit protection in demanding electrical distribution systems. As part of the ABB S800S high-performance MCB series, it combines robust circuit protection with high breaking capacity for industrial and commercial installations.
This circuit breaker features a Type B tripping characteristic, making it suitable for circuits with relatively low inrush currents, including resistive loads, lighting, control circuits and general electrical distribution. Thermal and electromagnetic tripping mechanisms provide reliable protection against sustained overloads and short-circuit faults.
With a rated current of 4 A, a two-pole configuration and a rated ultimate short-circuit breaking capacity of up to 50 kA, the S802S-B4 is engineered for applications requiring dependable multi-pole circuit protection and high fault interruption performance. Its modular construction supports straightforward installation in electrical distribution boards and control panels.
