This E-T-A 452-2-K34-FN2-75A is a high-performance, single-pole, thermal-magnetic circuit breaker designed for demanding applications. It utilizes a tease-free, trip-free, snap-action mechanism with a push-pull plunger for actuation. The breaker is panel mounted and suitable for extra-low voltage wiring systems in vehicles, defence equipment, and battery-powered machines.
Key electrical specifications include a current rating range of 50-100A, with this specific model at 75A, and a voltage rating of 28VDC. It offers an interrupting capacity of 6,000A and an auxiliary circuit rating of 0.5A at 28VDC. The typical life is rated at 2,500 operations at IN.
Environmental and mechanical robustness are ensured with an operating temperature range of -55 to +75°C, IP40 protection for the operating area, and resistance to vibration, shock, corrosion, and humidity as per relevant standards. The breaker has a typical volt drop of 90mV at 75A.
Approvals include UL 1077, CSA C22.2 No 235, and various military standards such as VG 95345. This makes it suitable for use in tracked vehicles, aircraft, and general-purpose applications where reliable circuit protection is essential.
