Typical applications
Technical data
Three pole, miniaturised, aircraft style 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, available in metric and US (AS 14154) configurations.
Advanced two-chamber design minimises contact contamination to
provide fail-safe operation. Temperature compensated with optional
auxiliary contacts, and fully approved for use on a wide range of
aircraft and equipment.
Various dummies are available without protective function, allowing
connection of pre-installed wiring without loads.
Aircraft systems and equipment (fixed wing and helicopters); other extra
low voltage wiring applications; defence equipment; communications
systems.
