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 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.
