High Performance Thermal Circuit Breaker 483-...
Description
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 clearly shows 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.
Typical applications
without auxiliary contact
Aircraft systems and equipment (fixed wing and helicopters); other
extra low voltage wiring applications; defence equipment;
communications systems.
