Why Choose the ABB S201M-Z40UC Miniature Circuit Breaker?
The ABB S201M-Z40UC is a high-performance single-pole miniature circuit breaker (MCB) designed for reliable overload and short-circuit protection in AC and DC electrical systems. Part of the ABB S200M UC / System pro M compact range, it combines a 40 A rated current, sensitive Type Z tripping characteristic and 10 kA short-circuit breaking capacity.
Developed for universal-current applications, the S201M-Z40UC provides flexible protection for both alternating-current and direct-current circuits. Its Type Z characteristic provides sensitive magnetic operation, making it particularly suitable for circuits where comparatively low fault currents require rapid protective disconnection.
With a 40 A nominal current, 1-pole configuration and compact modular construction, the S201M-Z40UC is well suited to industrial distribution, control equipment and specialised DC systems. ABB order code 2CDS271061R0558 identifies this exact 40 A Type Z model within ABB's DC / traction MCB portfolio.
