Why Choose the ABB ST201M-Z32 Miniature Circuit Breaker?
The ABB ST201M-Z32 is a compact and reliable single-pole miniature circuit breaker (MCB) designed to provide supplementary overcurrent and short-circuit protection for industrial control equipment and electrical systems. As part of the ABB ST200M series, it combines thermal-magnetic protection with a sensitive Z tripping characteristic and compliance with UL 1077 requirements.
Rated at 32 A, the ST201M-Z32 uses a Z tripping characteristic, making it particularly suitable for circuits requiring sensitive magnetic protection at relatively low multiples of rated current. This characteristic supports the protection of electronic equipment, control circuits and other loads where rapid response to excessive current is important.
The ST201M-Z32 is a 1-pole device with ABB order code 2CDS271334R0538. With a 15 kA short-circuit breaking capacity and UL 1077 classification, it provides dependable supplementary protection for industrial automation, control and electrical equipment circuits.
