Why Choose the ABB SU201DC-Z32 Miniature Circuit Breaker?
The ABB SU201DC-Z32 is a high-performance single-pole DC miniature circuit breaker (MCB) designed to protect electrical circuits against overload and short-circuit conditions. As part of the ABB SU200DC series, it is specifically developed for direct-current applications in commercial, industrial and traction-related electrical systems.
Featuring a Type Z tripping characteristic, the SU201DC-Z32 provides sensitive overcurrent protection for circuits and equipment requiring rapid magnetic operation at comparatively low multiples of rated current. This makes Type Z protection particularly suitable for electronic equipment, control circuits and other sensitive DC loads where responsive protection against overcurrent is required.
With a rated current of 32 A, a single-pole configuration and a short-circuit rating of 14 kA, the SU201DC-Z32 provides robust circuit protection for demanding DC installations. ABB order code 2CDS271527R0538 identifies this specific 32 A Type Z version of the SU201DC range.
