This makes it the correct choice for protecting control transformers, PLC power supplies, and analog I/O loops where a standard Curve C would allow fault current to persist long enough to cook the load.","metaTitle":"ABB S201-Z1 MCB 1P Z 1A 277V, 6 kA","metaDescription":"ABB S201-Z1 miniature circuit breaker, 1-pole, Trip Curve Z, 1 A, 277 VAC, 6 kA interrupting capacity.
