Why Choose the ABB SH201-B40 Miniature Circuit Breaker?

The ABB SH201-B40 is a compact and reliable single-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overload and short-circuit faults. As part of the ABB SH200 series, it provides dependable thermal-magnetic protection for residential and similar electrical installations where safe, space-efficient DIN-rail circuit protection is required.

With a rated current of 40 A and a Type B tripping characteristic, the SH201-B40 is suited to circuits with relatively low inrush currents. Its thermal release responds to sustained overload conditions, while the magnetic release provides rapid disconnection when a short-circuit fault occurs, helping protect conductors and connected equipment.

The SH201-B40 provides a rated short-circuit capacity of 6 kA and uses a compact single-pole modular format. This combination makes it a practical choice for residential and similar distribution systems requiring dependable 40 A circuit protection.

Reliable Protection for Electrical Circuits

Miniature circuit breakers such as the ABB SH201-B40 use thermal and magnetic release mechanisms to protect electrical wiring against overcurrent faults. The thermal element responds to sustained overload currents that could otherwise cause excessive conductor heating, while the magnetic release operates rapidly when a high short-circuit current occurs.

The Type B characteristic is intended for circuits with comparatively low normal inrush currents. Combined with its 40 A rating, single-pole construction and 6 kA short-circuit capacity, the SH201-B40 provides practical protection for residential and similar low-voltage distribution systems.

Typical Applications

• Residential electrical distribution boards.
• Higher-current final circuits.
• Resistive electrical loads.
• Circuits with relatively low normal inrush currents.
• Light-commercial electrical installations.
• DIN-rail consumer units and distribution equipment.
