The E-T-A 482-G212-K1M1-A1S0-40A is a high-performance, single-pole thermal circuit breaker featuring a tease-free, trip-free, snap-action mechanism with manual push/pull actuation. It is designed for panel mounting and includes an indicator band on the push button to clearly show the tripped/off position.
This circuit breaker has a current rating of 40A and supports voltage ratings of 115V AC (400 Hz) and 28V DC. It is suitable for extra-low voltage wiring systems in vehicles for land, sea, and air, as well as battery-powered machines and process control applications.
Key technical specifications include an ambient temperature range of -55 to +75 °C, an interrupting capacity of 5,000 A at 72 VDC (UL 1077), and degrees of protection IP40 for the operating area and IP00 for the terminal area. The breaker also meets stringent environmental and mechanical test standards for vibration, shock, corrosion, and humidity.
Mounting is achieved via a threadneck panel mount design. The breaker is built to EN 60934 standards and is approved by CSA C22.2 No 235, IEC 60934, and UL1077.
