High Performance Thermal Circuit Breaker 5140
Description
Three pole, aircraft style thermal circuit breaker with trip-free mechanism
and push/pull on/off manual actuation. An indicator band on the
push button clearly shows the tripped/off position. Threadneck panel
mounted, temperature compensated, with optional auxiliary contacts.
The robust design is well suited to extremely harsh conditions. In the
event of an overload in one, two or three phases all three poles will
be disconnected.
Various dummies are available without protective function, allowing
connection of pre-installed wiring without loads.
Typical applications
Land vehicles, aircraft, watercraft, special vehicles.
