This E-T-A 483-G411-K1M1-A1S0Z-30A is a single-pole, miniaturized thermal circuit breaker with a snap-action mechanism. It is designed for manual push-pull actuation and panel mounting, suitable for metric and US configurations.
The circuit breaker operates at 115 VAC (300-800 Hz) and 28 VDC, with a current rating range of 1 to 35 A, specifically 30A for this model. It offers a high interrupting capacity of 2,000 A at 115 VAC and 6,000 A at 28 VDC. The device is temperature compensated from -55 °C to +125 °C, ensuring reliable operation across a wide ambient temperature range.
Typical applications include aircraft systems and equipment, defense equipment, and communications systems. The advanced two-chamber design contributes to fail-safe operation. It meets stringent environmental and mechanical testing standards, including vibration, shock, humidity, and corrosion resistance.
The voltage rating is 115 V AC (300 Hz to 800 Hz) and 28 V DC.
The current rating range is 1 to 35 A, with this specific model rated at 30 A.
The ambient temperature range is -55 °C to +125 °C.
This circuit breaker is designed for panel mounting.
The interrupting capacity at AC 115 V (400 Hz) is 2,000 A for a 5A rating and 2,500 A for ratings 7.5A to 35A.
The interrupting capacity at DC 28 V is 6,000 A for ratings 1A to 25A and 4,000 A for ratings 30A to 35A.
The typical mechanical life is 20,000 operations.
