The E-T-A 452-K34-FN2-S1-100A is a high-performance thermal circuit breaker with a tease-free, trip-free, snap-action mechanism. It offers manual push/pull actuation and an indicator band to clearly show the tripped/off position.
This single-pole breaker is rated for 100A and operates at 28V DC, with an AC 115V (400 Hz) rating available upon request. It features a panel mount design with screw terminals suitable for aircraft specifications.
Key technical data includes an interrupting capacity of 6,000A (Icn and UL 1077), an operating temperature range of -55°C to +75°C, and an insulation resistance greater than 100 MΩ. The breaker is designed to withstand vibration, shock, and corrosion, making it suitable for demanding applications.
Typical applications include extra-low voltage wiring systems on vehicles for land, sea, and air, as well as defence equipment and battery-powered machines.
