2CDS272334R0131 ABB ST202M-D13 Miniature Circuit Breaker 15kA 2P D 13A UL 1077

Why Choose the ABB ST202M-D13 Miniature Circuit Breaker?

The ABB ST202M-D13 is a high-performance two-pole miniature circuit breaker (MCB) designed to provide supplementary overcurrent and short-circuit protection in industrial, commercial and machine-building electrical systems. As part of the ABB System pro M compact ST200M series, it combines a D tripping characteristic with a 13 A rated current for dependable protection of circuits supplying equipment with high starting and inrush currents.

Designed for applications requiring UL 1077 supplementary protection, the ST202M-D13 provides two-pole circuit protection in a compact DIN rail format. Its D tripping characteristic is particularly suited to circuits supplying transformers, inductive equipment and other electrical loads that can produce substantial transient currents during start-up.

With a rated current of 13 A, a two-pole configuration and a short-circuit breaking capacity of 15 kA, the ST202M-D13 provides robust supplementary protection for industrial control and electrical equipment. Its compact modular construction makes it suitable for control panels, machinery and OEM systems where dependable protection and efficient use of installation space are important.
