The E-T-A 1626-3-20A is a single pole, thermal miniaturized circuit breaker suitable for automotive applications. It is designed to fit into fuse blocks compliant with ISO 8820-3, Type F standards.
This circuit breaker features a 20A current rating and a maximum voltage rating of 29 VDC. It has a thermal breaker type and a push-push actuator. The device operates within an ambient temperature range of -40 to +85 °C and offers protection for electrical systems in passenger cars, trucks, buses, and watercraft.
Key technical data includes a service short-circuit breaking capacity of 300 operations at 2 x IN and an ultimate short-circuit breaking capacity of at least 3 break operations at 150 A. The circuit breaker has a fast characteristic curve for ratings 7.5A through 30A. It also meets stringent environmental and mechanical testing standards, including vibration, shock, corrosion, and humidity resistance.
Mounting is designed for a holder type, and the device offers various reset options, including automatic reset for DC 12V systems and an open circuit version with modified reset to SAE standards. The circuit breaker will reset after the load is removed, making it suitable for inaccessible locations.
