Why Choose the ABB ST202M-K1.6 Miniature Circuit Breaker?
The ABB ST202M-K1.6 is a high-performance 2-pole miniature circuit breaker (MCB) designed to provide reliable supplementary overcurrent and short-circuit protection for industrial control equipment and electrical circuits. As part of the robust ABB ST200M series, it combines a 1.6 A rated current with a Type K tripping characteristic for dependable protection of circuits containing inductive loads.
Designed for supplementary protection in accordance with UL 1077, the ST202M-K1.6 also complies with IEC/EN 60947-2 and CSA 22.2 No. 235 requirements. Its thermal-magnetic operating principle provides automatic interruption during overload and short-circuit conditions, while the compact modular construction enables straightforward installation in industrial control panels and electrical assemblies.
With two protected poles, a rated current of 1.6 A and a K characteristic, this breaker is particularly suitable for control circuits and equipment where normal operating inrush currents must be accommodated without compromising circuit protection. ABB order code 2CDS272334R0257 provides precise identification for specification, procurement and replacement.

Reliable Supplementary Circuit Protection
Miniature circuit breakers such as the ABB ST202M-K1.6 automatically disconnect protected circuits when excessive current results from an overload or short circuit. Unlike a fuse, the breaker can be reset after the fault has been identified and corrected, helping simplify maintenance in industrial machinery, automation systems and electrical control equipment.
The Type K operating characteristic is particularly useful for inductive equipment and circuits that can experience elevated starting currents during normal operation. Combined with the ST200M series' compact modular construction and high short-circuit performance, this makes the ST202M-K1.6 a practical supplementary protection device for demanding industrial installations.
Typical Applications
- Industrial control panels and automation equipment.
- Control and auxiliary circuits.
- Inductive electrical loads.
- Industrial machinery and OEM equipment.
- Power supply and equipment protection circuits.
- Supplementary circuit protection where UL 1077 devices are specified.
