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 °C 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
Aircraft systems and equipment (fixed wing and helicopters);
other extra low voltage wiring applications; defence equipment;
communications systems.
