2CDS272061R0548 ABB S202M-Z35UC MCB 10kA 2P Type Z 35A

Why Choose the ABB S202M-Z35UC Miniature Circuit Breaker?

The ABB S202M-Z35UC 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 power-distribution applications.

This model combines a 35 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-Z35UC particularly suitable for electronic equipment, control systems and other circuits where sensitive overcurrent protection is required.

With its two-pole configuration, the S202M-Z35UC is suitable for applications up to 400 V AC and 440 V DC and provides a 10 kA short-circuit breaking capacity. Its universal-current design extends ABB's established System pro M compact platform to demanding AC and DC installations. ABB order code 2CDS272061R0548 identifies this exact 35 A Type Z configuration.
