The E-T-A 413-K34-FN2-40A is a high-performance thermal circuit breaker featuring a tease-free, trip-free, snap-action mechanism with manual push/pull actuation. This single-pole breaker is designed for panel mounting and is suitable for extra-low voltage wiring systems in various vehicles and defence equipment.
Key electrical specifications include a voltage rating of 115 VAC (400 Hz) or 28 VDC, and a current rating range of 30-55 A for the -FN2 version. The breaker boasts a high interrupting capacity of 1,000 A at 115 VAC (400 Hz) and 6,000 A at 28 VDC. It is built to withstand demanding environmental conditions, operating within an ambient temperature range of -55 to +75 °C.
Mechanical and environmental features include a degree of protection of IP40 for the operating area and IP00 for the terminal area. It meets stringent vibration and shock resistance standards, including 10 g vibration and 50 g shock. The breaker is also designed for corrosion and humidity resistance.
Approvals include CSA C22.2 No 235 and UL1077, ensuring reliability in critical applications. The typical operational life is rated at 2,000 operations at nominal current. The breaker is panel mounted and features a push-pull plunger actuator.
