This E-T-A 483-G411-K1M1-A1S0ZN-20A is a high-performance, miniaturized thermal circuit breaker. It utilizes a tease-free, trip-free, snap-action mechanism with manual push-pull actuation for on/off control. The breaker is designed for panel mounting and features a threadneck configuration.
Key electrical specifications include a voltage rating of 115V AC (300 Hz to 800 Hz) and 28V DC. The current rating is 20A. It offers an interrupting capacity of 2,000A at 115V AC (400 Hz) and 6,000A at 28V DC.
The circuit breaker operates within an ambient temperature range of -55°C to +125°C and is temperature compensated across this range. It meets various environmental and mechanical standards, including IP40 protection for the operating area and IP00 for the terminal area, along with specifications for vibration, shock, corrosion, and humidity.
Typical applications include aircraft systems and equipment, defense equipment, and communications systems, as well as other extra-low voltage wiring applications. It is approved by agencies such as CSA and UL.
