The E-T-A 483-G111-K1M1-A1S1Z-25A is a high-performance, single-pole, miniaturized thermal circuit breaker. It features a tease-free, trip-free, snap-action mechanism with manual push/pull on/off actuation, compliant with EN 60934.
This circuit breaker is designed for demanding applications, including aircraft systems, defence equipment, and communications systems. It operates within a current rating range of 1 to 35A and has a voltage rating of 115V AC (300 Hz to 800 Hz) and 28V DC. The device is temperature compensated from -55°C to +125°C.
Key technical specifications include an AC interrupting capacity of 2,000A at 115V (400 Hz) for 5A and 2,500A for 7.5-35A, and a DC interrupting capacity of 6,000A at 28V for 1-25A and 4,000A for 30-35A. It offers a degree of protection of IP40 for the operating area and IP00 for the terminal area.
The unit is designed for panel mounting and features a threadneck configuration. It has undergone rigorous environmental testing, including vibration, shock, corrosion, and humidity resistance, making it suitable for harsh operating conditions. Approvals include UL 1077 and CSA C22.2 No 235.
It is rated for 115 V AC (300-800 Hz) and 28 V DC.
