The E-T-A 583-G111-K1M1-A1S1U-3A is a high-performance thermal circuit breaker designed for demanding applications, particularly in aircraft systems and equipment. This three-pole device utilizes a miniaturized, aircraft-style design with a tease-free, trip-free, snap-action mechanism and manual push-pull actuation.
Key technical specifications include a voltage rating of 200V AC (300 Hz to 800 Hz) and 28V DC, with a current rating of 3A. The breaker offers a current rating range from 1A to 30A and features an auxiliary circuit rated at 0.5A DC 28V. It is designed for panel mounting and has an operating area degree of protection of IP40.
Environmental and mechanical robustness are key features, with resistance to vibration, shock, and corrosion. The operating temperature range is -55°C to 125°C (or -55°C to 90°C for ratings above 15A). Typical mechanical life is rated at 20,000 operations.
Typical applications include fixed-wing and helicopter aircraft systems, defense equipment, and communications systems. Its advanced two-chamber design minimizes contact contamination for fail-safe operation.
It is rated for 200VAC (300-800Hz) and 28VDC.
The rated current is 3A.
It uses a push-pull plunger actuator.
It is a 3-pole circuit breaker.
For currents ≤15A, it operates from -55°C to 125°C. For currents >15A, the range is -55°C to 90°C.
It is designed for panel mounting.
Interrupting capacity varies by current: at 200VAC, 1000A for ≤4A, 2000A for 5A, 2500A for 7.5-25A, 1500A for 30A. At 28VDC, 6000A for 1-25A, 4000A for 30A.
