Why Choose the ABB S202-B1 Miniature Circuit Breaker?
The ABB S202-B1 is a compact and reliable two-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits. As part of the established ABB System pro M compact S200 MCB series, it combines thermal overload protection with electromagnetic short-circuit protection for dependable circuit protection in commercial and industrial electrical installations.
Featuring a Type B tripping characteristic, the S202-B1 is suited to circuits with relatively low inrush currents, including control, auxiliary, instrumentation and general electrical loads. Both poles are protected, providing simultaneous two-pole circuit protection and disconnection in a compact DIN-rail-mounted device.
With a rated current of 1 A, a two-pole configuration and breaking capacities of 6 kA to IEC/EN 60898-1 and 10 kA at 400 V AC to IEC/EN 60947-2, the S202-B1 provides dependable protection for low-current circuits. ABB order code 2CDS252001R0015 identifies this specific 1 A Type B model within the S200 range.

Reliable Two-Pole Circuit Protection
Miniature circuit breakers such as the ABB S202-B1 automatically disconnect a circuit when excessive current occurs. The S200 design combines a thermal tripping mechanism for overload protection with an electromagnetic mechanism for rapid response to short-circuit currents, helping protect conductors, equipment and connected loads.
The S202-B1 incorporates two protected poles and a Type B tripping characteristic, making it particularly suitable for low-current circuits with relatively modest normal inrush currents. Its two-pole configuration provides simultaneous disconnection, while the modular DIN-rail format makes it suitable for distribution boards, control panels and other electrical assemblies.
Typical Applications
- Low-current control circuits.
- Industrial control and automation panels.
- Instrumentation and auxiliary circuits.
- Commercial electrical installations.
- Two-pole electrical distribution circuits.
- Distribution boards and switchgear assemblies.
