The E-T-A 1620-2-20A is a single-pole, thermal miniaturized circuit breaker (Mini-CBE) 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 20A and operates with a nominal voltage of 12VDC, with a maximum voltage rating of 14.5VDC. It features an automatic reset function, ensuring that the circuit breaker will reset after the load is removed. The breaker meets the requirements of SAE J553 and is suitable for installation in hard-to-reach locations.
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 150A. The operating ambient temperature range is -40°C to +85°C. The device is designed to withstand vibration up to 10g and shock up to 50g.
Environmental specifications include corrosion resistance tested for 48 hours in 5% salt mist and humidity resistance tested for 240 hours in 95% RH. The operating area has a degree of protection of IP50 for versions -1 and -2, and IP40 for version -3. The terminal area is rated IP00. Its compact design and approximate mass of 3g make it ideal for space-constrained automotive electrical systems.
