The E-T-A 3131-AF1PT-000000-1Y2-5A is a single-pole thermal circuit breaker designed for overcurrent protection in panel-mount applications. It is rated for 5A continuous current at 240V AC (and 28V DC per datasheet). The breaker features a yellow illuminated actuator, with nominal illumination voltage of 10-14V. The operating temperature range spans -20°C to +60°C, making it suitable for indoor industrial environments.
The interrupting capacity meets UL 1077 requirements: 3000A at 240V AC and 2500A at 32V DC for ratings up to 16A. The breaker is housed in a compact package with flange mounting, typical mass of 30g, and offers IP66 protection on the operating area for dust and water resistance. Internal resistance ranges from 0.9 Ohm at 1A to less than 0.02 Ohm at 20A. The device has been tested for vibration (5g), shock (25g), corrosion (96h salt mist), and humidity (240h at 95% RH) per IEC standards.
The breaker is rated for 240V AC (and 28V DC per datasheet).
The operating temperature range is -20°C to +60°C (-4°F to +140°F).
Panel mount with flanges.
For UL 1077: 3000A at 240V AC and 2500A at 32V DC. For IEC: up to 200A for ratings 2.5-20A.
Yes, a yellow illumination with nominal voltage 10-14V.
The typical internal resistance at 5A is 0.0325 Ohm.
