2CDS272061R0158 ABB S202M-Z0.5UC MCB 10kA 2P Type Z 0.5A

Why Choose the ABB S202M-Z0.5UC Miniature Circuit Breaker?

The ABB S202M-Z0.5UC is a high-performance two-pole 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 universal-current capability with a low 0.5 A current rating for precise protection of sensitive control, signalling and auxiliary circuits.

This model combines a 0.5 A rated current with a Type Z tripping characteristic. The sensitive Z characteristic provides rapid magnetic response at comparatively low fault-current multiples, making it particularly suitable for electronic equipment, control circuits and other loads requiring sensitive overcurrent protection.

With its two-pole configuration, 10 kA short-circuit breaking capacity and suitability for both AC and DC applications, the S202M-Z0.5UC provides flexible circuit protection for industrial and transportation electrical systems. Its universal-current design supports DC applications up to 440 V DC with two poles, while ABB order code 2CDS272061R0158 identifies this exact 0.5 A Type Z model.
