The E-T-A 482-G111-K1M1-A1S0-3A is a high-performance, single-pole thermal circuit breaker designed for reliable overcurrent protection. It utilizes a tease-free, trip-free, snap-action mechanism with manual push/pull actuation.
Key electrical specifications include a 3A current rating and a voltage rating of 230V AC (50/60 Hz) or 28V DC. The breaker is suitable for extra-low voltage wiring systems found in vehicles and battery-powered machines.
This thermal circuit breaker is designed for panel mounting with a threadneck design (M12x1 nickel plated) and features screw terminals with an M4 metric thread. It offers a degree of protection of IP40 in the operating area and IP00 at the terminals.
Environmental testing includes resistance to vibration (10g), shock (50g), corrosion (salt mist), and humidity. The typical mechanical life is 10,000 operations, with 5,000 operations at the rated current (IN).
