Why Choose the ABB ST202M-D10 Miniature Circuit Breaker?
The ABB ST202M-D10 is a compact and reliable two-pole miniature circuit breaker (MCB) designed for supplementary overcurrent protection in industrial control, automation and electrical equipment applications. As part of the proven ABB ST200M series, it combines a 10 A rated current with a D tripping characteristic for circuits where relatively high transient or starting currents may occur.
Designed to meet UL 1077 requirements for supplementary protectors, the ST202M-D10 provides thermal-magnetic protection against overload and short-circuit conditions. Its two-pole configuration allows simultaneous protection and switching of two conductors, while the modular DIN-rail format supports straightforward installation in control panels, machinery and electrical distribution assemblies.
With a rated current of 10 A, D characteristic and an ultimate short-circuit breaking capacity of 15 kA at 400 V AC and 125 V DC according to IEC/EN 60947-2, the ST202M-D10 provides dependable protection for demanding industrial circuits. The ABB order code for this device is 2CDS272334R0101.

Reliable Supplementary Circuit Protection
Miniature circuit breakers such as the ABB ST202M-D10 automatically interrupt a circuit when excessive current is detected. Thermal protection responds to sustained overload conditions, while the magnetic mechanism provides rapid operation during severe overcurrent and short-circuit events.
The D characteristic is designed for applications where equipment can produce comparatively high transient currents during energisation. This makes the ST202M-D10 particularly useful in industrial control and machinery applications where reliable protection must be combined with tolerance of normal equipment starting currents.
Typical Applications
- Industrial machinery and automation panels.
- Control and auxiliary circuits.
- Equipment-level supplementary overcurrent protection.
- Circuits with elevated starting or inrush currents.
- Industrial electrical distribution assemblies.
- OEM control cabinets and machine-building applications.
