High Performance Thermal Circuit Breaker 4140-...
Description
Single pole, thermal circuit breaker with trip-free mechanism, push/pull
on/off manual actuation (M-type TO CBE to EN 60934) and temperature
compensation. An indicator band on the push button clearly shows the
tripped/off position. The robust design makes type 4140 suitable for
extremely harsh conditions.
Various dummies are available without protective function, allowing
connection of pre-installed wiring without loads.
Typical applications
Land vehicles, aircraft, watercraft, special vehicles.
