ABB S201MT-Z1NAH01 miniature circuit breaker with 1 A rated current, Z trip characteristic, 1P plus switched neutral configuration and 10 kA breaking capacity for railway, industrial and automation applications.
The ABB S201MT-Z1NAH01 is a high performance miniature circuit breaker (MCB) from the ABB S200MT series, developed to provide reliable overload and short circuit protection in railway, traction, industrial and commercial electrical installations. Featuring a Z characteristic trip curve, this breaker is particularly suited to protecting sensitive electronic equipment and control circuits that require rapid fault disconnection.
Designed with a 1P + switched neutral configuration, the S201MT-Z1NAH01 protects the live conductor while simultaneously switching the neutral conductor, helping improve circuit isolation. Its 1 A rated current and 10 kA breaking capacity make it an excellent solution for low current applications where dependable protection is essential.
The compact DIN rail mounted design enables straightforward installation inside distribution boards and control panels. Fully compatible with ABB System pro M Compact accessories, the S201MT-Z1NAH01 offers excellent flexibility for panel builders, OEMs and maintenance engineers.
Miniature circuit breakers automatically disconnect electrical circuits when overload or short circuit conditions occur, helping protect equipment from damage and improving system reliability. The ABB S201MT-Z1NAH01 is specifically suited to applications where sensitive electronic devices require fast fault clearance.
Its Z characteristic provides rapid magnetic tripping, making it ideal for PLCs, instrumentation, signalling systems, control electronics and other low current circuits commonly used in industrial automation and railway applications.
