Why Choose the ABB S202M-D50 Miniature Circuit Breaker?
The ABB S202M-D50 is a robust two-pole miniature circuit breaker (MCB) from the trusted ABB System pro M compact S200M series. It is designed to provide reliable protection against overloads and short circuits in commercial, industrial and OEM electrical installations.
Featuring a D curve tripping characteristic and a 50 A rated current, the S202M-D50 is suitable for circuits with high inrush currents, including transformers, power supplies, industrial equipment and selected motor-related loads. Its current-limiting design helps reduce fault energy while protecting connected equipment and electrical wiring.
The ABB S202M-D50 is designed for standard DIN rail mounting inside distribution boards, switchboards and industrial control panels. Its compact modular housing, durable construction and compatibility with ABB System pro M accessories make it a practical choice for professional electrical installations.
Key Advantages
- Reliable two-pole miniature circuit breaker for circuit protection.
- 50 A rated current for low voltage electrical circuits.
- D curve tripping characteristic for high inrush current applications.
- 10 kA short-circuit breaking capacity for dependable protection.
- DIN rail mounting for quick installation in control panels.
- Compatible with ABB System pro M compact accessories.
Key Features
- ABB System pro M compact S200M series.
- Two protected poles (2P).
- 50 A rated current.
- D characteristic tripping curve.
- 10 kA rated short-circuit capacity.
- Suitable for AC applications up to 400 V AC.
- Current-limiting thermal and magnetic trip mechanisms.
- Compact modular DIN rail mounted design.
Reliable Protection for Electrical Installations
The ABB S202M-D50 uses thermal and magnetic tripping mechanisms to protect electrical circuits from overload and short-circuit faults. The thermal trip responds to sustained overloads, while the magnetic trip provides rapid disconnection during short-circuit conditions.
Its D curve characteristic is designed for applications where higher starting currents are expected. This helps reduce nuisance tripping during energisation while maintaining effective protection for cables, equipment and electrical installations.
Typical Applications
- Industrial control panels.
- Commercial electrical distribution boards.
- Transformer and power supply circuits.
- Industrial equipment with high inrush currents.
- Motor control and machinery circuits.
- OEM machinery and panel building applications.
