This E-T-A 452-K34-LN2-S1-100A is a single-pole, high-performance thermal-magnetic circuit breaker. It utilizes a tease-free, trip-free, snap-action mechanism with push/pull on/off actuation, clearly indicating tripped status via an indicator band on the push button. Designed for threadneck panel mounting, it is suitable for general-purpose applications in tracked vehicles and aircraft.
Key electrical specifications include a voltage rating of 28V DC and a current rating range of 50 to 100A, with this specific model rated at 100A. It offers an interrupting capacity of 6,000A and an auxiliary circuit rating of 0.5A at 28V DC. The operating ambient temperature range is -55°C to +75°C.
Environmental and mechanical robustness are ensured through features like IP40 protection for the operating area, resistance to vibration (10g), shock (50g), corrosion (96 hours salt mist), and humidity (240 hours at 95% RH). It also meets explosion proof requirements per VG 95210 and MIL-STD-202.
Approvals include CSA C22.2 No 235 and UL1077, with specific ratings also noted for Bw, QPL Canada, and QPL Sweden standards. This circuit breaker is ideal for extra-low voltage wiring systems in various vehicle types, defense equipment, and battery-powered machinery.
