Why Choose the ABB S802S-UCB40 Miniature Circuit Breaker?

The ABB S802S-UCB40 is a high-performance 2-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits in demanding installations. Part of the ABB S800S high-performance MCB series, it combines a 40 A current rating with a Type B tripping characteristic and high fault-interruption capability.

With a rated current of 40 A and a short-circuit breaking capacity of 50 kA, the S802S-UCB40 provides robust protection where substantial prospective fault currents may occur. Its Type B characteristic is suited to appropriately designed circuits with comparatively low functional inrush currents, providing responsive protection against abnormal overcurrent conditions.

The S802S-UCB40 uses a 2-pole configuration and ABB's proven S800S high-performance architecture. Its current-limiting operation and compact modular construction make it suitable for professional electrical distribution, control and equipment applications requiring dependable circuit protection.
