High Performance Thermal-Magnetic Circuit Breaker 452-...
Description
Single pole high performance thermal-magnetic circuit breaker, with
tease-free, trip-free, snap action mechanism and push/pull on/off
actuation (M-type TM CBE to EN 60934). An indicator band on the
push button clearly shows the tripped/off position. Threadneck panel
mounted in tracked vehicle and aircraft/general purpose versions, with
optional fast acting magnetic characteristics and auxiliary contacts.
Typical applications
Extra low voltage wiring systems on all types of vehicle for land, sea
and air; defence equipment; battery powered machines.
