2CDS272061R0404 ABB S202M-C40UC MCB 10kA 2P Type C 40A

Why Choose the ABB S202M-C40UC Miniature Circuit Breaker?

The ABB S202M-C40UC 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 high short-circuit performance for industrial, transportation, control and power-distribution applications.

This model combines a 40 A rated current with a Type C tripping characteristic. Type C protection accommodates moderate starting and inrush currents while maintaining effective overload and short-circuit protection, making the S202M-C40UC suitable for machinery, control equipment, auxiliary systems and general-purpose distribution circuits.

With its two-pole configuration, the S202M-C40UC provides coordinated protection and switching across two conductors. It offers a 10 kA rated short-circuit capacity at 253 V AC, 400 V AC and 440 V DC, together with an ultimate short-circuit breaking capacity of 25 kA at 220 V DC. ABB order code 2CDS272061R0404 identifies this exact 40 A Type C universal-current MCB.
