Description

Typical applications

Technical data

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.

Land vehicles, aircraft, watercraft, special vehicles.
