Why Choose the ABB S402M-UCZ4 DC Miniature Circuit Breaker?
The ABB S402M-UCZ4 is a 2-pole miniature circuit breaker (MCB) designed for reliable overload and short-circuit protection in DC electrical distribution systems. Part of the ABB S400M-UC range for the SMISSLINE TP plug-in system, this model combines a 4 A rated current, Type Z tripping characteristic and a two-pole configuration for DC applications.
ABB identifies order code 2CCS572001R1048 as the S402M-UCZ4 with a 4 A current rating. The Type Z characteristic provides sensitive overcurrent protection for appropriate circuits and equipment where lower magnetic tripping thresholds are required.
The two-pole S402M-UCZ4 is designed for DC applications up to 440 V DC when connected with both poles in accordance with ABB's specified DC connection arrangement. Its SMISSLINE plug-in design supports efficient integration into compatible modular distribution systems, while its compact two-module construction helps conserve panel space.
