An MCB is a type of electrical switch that operates automatically. Miniature circuit breakers are designed to protect an electrical circuit from harm caused by excessive current. To protect against electrical failures and equipment failure, they are designed to trip upon an overload or short circuit.
Compact Home SH200 miniature circuit breakers are current limiting. They have two different tripping mechanisms, the delayed thermal tripping mechanism for overload protection and the electromechanic tripping mechanism for short circuit protection. They are available in different characteristics (B,C), configurations (1P,1P+N,2P,3P,3P+N,4P), breaking capacities (up to 6 kA at 230/400 V AC) and rated currents (up to 40 A). All MCBs of the product range SH200 comply with IEC/EN 60898-1, allowing the use for residential applications.
