Why Choose the ABB S202M-Z25UC Miniature Circuit Breaker?
The ABB S202M-Z25UC is a high-performance two-pole universal-current miniature circuit breaker (MCB) designed to protect AC and DC electrical circuits against overloads and short circuits. Part of the ABB System pro M compact S 200 M UC series, it combines flexible AC/DC operation with sensitive Type Z protection for industrial, control, transportation and distribution applications.
This model combines a 25 A rated current with a Type Z tripping characteristic. The Z characteristic provides sensitive magnetic operation at comparatively low fault-current multiples, making the S202M-Z25UC particularly suitable for electronic equipment, control systems and other circuits where rapid response to overcurrent is required.
With its two-pole configuration and 10 kA rated short-circuit breaking capacity, the S202M-Z25UC provides coordinated protection and switching across two conductors. The universal-current design is suitable for AC and DC applications, including DC circuits up to 440 V DC with two poles. ABB order code 2CDS272061R0518 identifies this exact 25 A Type Z configuration.
