Why Choose the ABB S202M-D0.5 Miniature Circuit Breaker?
The ABB S202M-D0.5 is a precise and reliable two-pole miniature circuit breaker (MCB) from the trusted ABB System pro M compact S200M series. It is designed to protect low-current electrical circuits against overloads and short circuits in industrial, commercial and OEM applications.
Featuring a D curve tripping characteristic and a 0.5 A rated current, the S202M-D0.5 is particularly suitable for circuits with high inrush currents, including control transformers, power supplies, solenoids and sensitive automation circuits. Its current-limiting design helps reduce fault energy while protecting connected equipment and electrical wiring.
The ABB S202M-D0.5 is designed for standard DIN rail mounting inside electrical distribution boards, switchboards and industrial control panels. Its compact modular construction and compatibility with ABB System pro M accessories make it a practical choice for professional panel builders and electrical contractors.
Key Advantages
- Reliable two-pole miniature circuit breaker for low-current circuit protection.
- 0.5 A rated current for sensitive control and auxiliary circuits.
- D curve tripping characteristic for high inrush current applications.

Reliable Protection for Control and Auxiliary Circuits
The ABB S202M-D0.5 uses thermal and magnetic tripping mechanisms to protect electrical circuits from overload and short-circuit faults. The thermal trip responds to sustained overload conditions, while the magnetic trip provides rapid disconnection during short-circuit faults.
Its D curve characteristic is designed for circuits where higher starting currents may occur during energisation. This helps reduce nuisance tripping while maintaining effective protection for sensitive control equipment, auxiliary circuits and industrial automation systems.
Typical Applications
- Industrial control panels.
- Commercial electrical distribution boards.
- Control transformer circuits.
- Power supplies and auxiliary circuits.
- Solenoid and automation equipment.
- OEM machinery and panel building applications.
