Why Choose the ABB S202-B2 Miniature Circuit Breaker?
The ABB S202-B2 is a 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 series, it provides current-limiting protection for residential, commercial and industrial electrical distribution systems.
The S202-B2 incorporates two complementary tripping mechanisms. A delayed thermal mechanism provides overload protection, while an electromechanical mechanism responds rapidly to short-circuit faults. This combination helps protect cables, connected equipment and electrical installations while supporting dependable long-term operation.
With a 2 A rated current, a B curve tripping characteristic, a two-pole configuration and a 6 kA rated breaking capacity, the ABB S202-B2 is well suited to low-current circuits with limited inrush current. Its compact DIN rail format makes it suitable for control circuits, lighting systems, instrumentation and electrical distribution panels.

Reliable Protection for Low-Current Circuits
The ABB S202-B2 automatically disconnects an electrical circuit when excessive current is detected. Its thermal tripping mechanism responds to sustained overload conditions, while its electromagnetic mechanism provides rapid protection against short-circuit currents.
The B curve characteristic is intended for circuits with relatively low starting currents. This makes the S202-B2 suitable for correctly designed lighting, control, instrumentation and resistive-load circuits where sensitive and dependable protection is required.
Typical Applications
- Industrial control and auxiliary circuits.
- Lighting and resistive-load circuits.
- Instrumentation and monitoring equipment.
- Commercial distribution boards.
- Building automation systems.
- OEM machinery and electrical control panels.
