|Catalog Description|Miniature Circuit Breaker - S200MT - 3P - K - 40 ampere|
||S200MT miniature circuit breakers are designed especially for traction and railway|
||applications. Acc. NF F 16-101/102 the product range S200MT is classified with|
||Exigence 3, enabling the use in all parts of the vehicle. They are current limiting and|
||have two different tripping mechanisms, the delayed thermal tripping mechanism for|
||overload protection and the electromechanic tripping mechanism for short circuit|
|Long Description|protection. They are available in different characteristics (C,D,K,Z), configurations|
||(1P,1P+N,2P,3P,3P+N,4P), breaking capacities (up to 10 kA at 230/400 V AC) and rated|
||currents (up to 63A). All MCBs of the product range S200MT comply with IEC/EN|
||60898-1 and IEC/EN 609 47-2. All system pro M compact accessories can be used.|
||Including the bottom-fitting auxiliary contact S2C-Hxx providing the possibility of|
||50% space saving and the creation of group signals.|
