Why Choose the ABB SU201DC-Z16 Miniature Circuit Breaker?
The ABB SU201DC-Z16 is a specialised single-pole DC miniature circuit breaker (MCB) designed to provide reliable overload and short-circuit protection for sensitive electrical and electronic circuits. Part of the ABB SU200DC series, this model combines a 16 A rated current, Z tripping characteristic and high short-circuit rating for dependable protection in commercial and industrial DC systems.
The Z characteristic provides sensitive magnetic protection, making the SU201DC-Z16 particularly suitable for electronic equipment, control circuits and other applications where comparatively low overcurrents need rapid interruption. Its thermal-magnetic operating principle combines protection against sustained overload conditions with fast disconnection during short-circuit faults.
With a 14 kA short-circuit current rating, single-pole configuration and dedicated DC design, the SU201DC-Z16 provides robust circuit protection in a compact modular format. It is well suited to industrial control panels, automation systems, instrumentation and auxiliary DC circuits requiring sensitive Z-characteristic protection.
