ABB HSSH-B40 miniature circuit breaker with 40 A current rating, Type B tripping characteristic and 6 kA breaking capacity for reliable overload and short circuit protection in electrical installations.
£18.44
The ABB HSSH-B40 is a reliable single pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits in residential, commercial and light industrial installations. Commonly associated with the ABB SH201-B40 Compact Home SH200 range, this device provides dependable current limiting protection in a compact DIN rail mounted format.
This miniature circuit breaker uses two protection mechanisms: a delayed thermal trip for overload protection and an electromechanical magnetic trip for short circuit protection. Its compact modular design makes it suitable for consumer units, distribution boards and electrical panels where reliable circuit protection is required.
With a 40 A current rating and a Type B tripping characteristic, the ABB HSSH-B40 is suitable for standard electrical circuits with low inrush current, including lighting, socket outlet and general power distribution applications.
Miniature circuit breakers automatically disconnect a circuit when excessive current is detected. This helps protect cables, equipment and electrical systems from overheating, insulation damage and short circuit faults.
The Type B characteristic of the ABB HSSH-B40 makes it suitable for circuits with relatively low inrush current. This includes many standard lighting, socket and general power circuits used in domestic and commercial distribution systems.
