The E-T-A 483-G533-J1M1-B2S0ZN-30A is a high-performance, miniaturized, aircraft-style thermal circuit breaker designed for demanding applications. It operates with a single pole and features a tease-free, trip-free, snap-action mechanism with manual push/pull actuation.
This circuit breaker is rated for 115 VAC (300 Hz to 800 Hz) and 28 VDC, with a current rating of 30A. It offers an interrupting capacity of 2000A at 115V AC and 6000A at 28V DC. The device is temperature compensated from -55°C to +125°C.
Designed for panel mounting, the 483-G533-J1M1-B2S0ZN-30A has an ingress protection rating of IP40 for the operating area and IP00 for the terminal area. It meets various stringent standards, including CSA C22.2 No 235 and UL1077 approvals.
Typical applications include aircraft systems and equipment, defense equipment, communications systems, and other extra-low voltage wiring applications. Its robust construction and advanced two-chamber design ensure fail-safe operation.
The circuit breaker is rated for 115 VAC and 28 VDC.
The breaker is rated for 30A continuous current.
It uses a push-pull plunger actuator.
The operating temperature range is -55 to +125°C.
At 115 VAC (400 Hz) it is 2000A for 5A and 2500A for 7.5-35A. At 28 VDC it is 6000A for 1-25A and 4000A for 30-35A.
It is approved to UL 1077, CSA C22.2 No 235, and VG 95345 part 6.
The typical mechanical life is 20,000 operations.
