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. 1 Typical applications 483-... without auxiliary contact with auxiliary contact Aircraft systems and equipment (fixed wing and helicopters) other extra low voltage wiring applications defence equipment communications systems.
