This E-T-A 483-G411-K1M1-A1S0ZN-30A is a high-performance, single-pole, miniaturized thermal circuit breaker. It utilizes a tease-free, trip-free, snap-action mechanism with manual push/pull on/off actuation, conforming to EN 60934.
Key electrical specifications include a current rating range of 1 to 35 A and voltage ratings of 115 V AC (300 Hz to 800 Hz) and 28 V DC. The breaker is temperature compensated from -55 °C to +125 °C and offers an auxiliary circuit rating of 0.5 A at 28 V DC.
Designed for demanding applications, this aircraft-style breaker features a threadneck panel mount configuration and an indicator band on the push button to clearly show the tripped/off position. Its advanced two-chamber design ensures fail-safe operation. Approvals include CSA C22.2 No 235 and UL1077.
Typical applications include aircraft systems and equipment, defence equipment, communications systems, and other extra-low voltage wiring applications. The breaker meets stringent environmental and mechanical testing standards for vibration, shock, and corrosion.
It supports 115V AC (300 Hz to 800 Hz) and 28V DC.
The device functions within an ambient temperature range of -55°C to +125°C.
It is a single-pole device designed for one-line circuit protection.
The unit typically lasts 20,000 mechanical operations, or 10,000 operations at currents up to 25A.
An optional auxiliary contact is available, rated for 28V DC at 0.5A.
It is certified under CSA C22.2 No 235 and UL1077 standards.
