High Performance Thermal Circuit Breaker 412-...
Description
Single pole high performance thermal circuit breaker with tease-free,
trip-free, snap action mechanism and push/pull on/off manual actuation
(M-type TO CBE to EN 60934). An indicator band on the push button
clearly shows the tripped/off position. Threadneck panel mounted and
available in tracked vehicle, aircraft and general purpose versions.
Typical applications
Extra low voltage wiring systems on all types of vehicles for land, sea
and air; defence equipment; battery powered machines.
