High Performance Thermal Circuit Breaker 483-...
Technical data
Description
483-...
without auxiliary contact with auxiliary contact
Single 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 shows clearly the tripped/off position. Threadneck
panel mounted, available in metric and US (MS 3320) configurations.
Advanced two-chamber design contributes to fail-safe operation.
Temperature compensated from -55
°
to +125
°
C, with optional auxiliary
contacts, and fully approved for use on a wide range of aircraft and
equipment. Full military specification ensures suitability for the most
demanding applications. For three pole version see type 583.
Aircraft systems and equipment (fixed wing and helicopters); other
extra low voltage wiring applications; defence equipment;
communications systems.
