The E-T-A 1620-3-5A is a single pole, thermal miniaturized circuit breaker specifically engineered for automotive applications. It fits into fuse blocks designed to ISO 8820-3, Type F, offering protection for electrical systems in passenger cars, trucks, buses, and watercraft.
This circuit breaker has a current rating of 5A and a maximum voltage rating of 29V. It meets the requirements of SAE J553 and offers automatic reset functionality for DC 12V systems, with an optional open circuit version. The breaker operates within an ambient temperature range of -40°C to +85°C.
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 1 break operation at 2,000 A. It has undergone rigorous testing for vibration, shock, corrosion, and humidity to ensure reliability in demanding environments.
The 1620-3-5A features a push-to-reset actuator and a holder mounting type. Its compact design and clear color coding, corresponding to blade fuses of the same rating, make it suitable for installation in inaccessible locations.
