Why Choose the ABB S202M-B50 Miniature Circuit Breaker?
The ABB S202M-B50 is a compact and reliable 2-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits. As part of the ABB System pro M compact S200M series, it provides dependable protection for low voltage distribution systems used in commercial, industrial and residential installations.
This miniature circuit breaker uses both delayed thermal tripping for overload protection and electromechanical tripping for short circuit protection. Its B curve tripping characteristic makes it suitable for general purpose circuits with lower inrush currents, helping provide fast and consistent disconnection when fault conditions occur.
With a 50 A rated current, 2-pole configuration and 10 kA breaking capacity, the S202M-B50 is ideal for DIN rail mounted distribution boards, control panels and electrical enclosures where robust circuit protection and compact installation are required.
