Why Choose the ABB S402M-B10 Miniature Circuit Breaker?
The ABB S402M-B10 is a current-limiting miniature circuit breaker (MCB) designed to provide reliable overload and short-circuit protection in commercial and industrial electrical distribution systems. As part of the ABB SMISSLINE TP S400M series, it combines a 10 A rated current, Type B tripping characteristic and two-pole configuration with convenient plug-in installation.
The S402M-B10 incorporates two complementary tripping mechanisms: delayed thermal tripping for overload protection and electromagnetic tripping for short-circuit protection. Its Type B characteristic is suitable for circuits with relatively low starting and inrush currents, providing dependable protection for resistive loads, control circuits and general-purpose electrical distribution.
With a rated current of 10 A, a 2-pole configuration and a 10 kA rated short-circuit breaking capacity, the S402M-B10 provides compact and dependable circuit protection. ABB order code 2CCS572001R0105 identifies this specific SMISSLINE TP miniature circuit breaker.
