The E-T-A 1626-2-20A is a single pole, thermal miniature circuit breaker (Mini-CBE) specifically designed for automotive applications. It fits into fuse blocks compliant with ISO 8820-3, Type F. This model features an automatic reset function and a 20A current rating, with a maximum voltage rating of DC 14.5V.
This circuit breaker is suitable for protecting electrical systems in passenger cars, trucks, buses, and watercraft. It has a fast characteristic curve and can continuously hold 70% of its rated current. The operating temperature range is -40°C to +85°C. The breaker is housed in a compact package with a mass of approximately 3g and offers an operating area protection of IP40.
Key technical data includes a service short-circuit breaking capacity of 300 operations at 2x IN and an ultimate short-circuit breaking capacity of at least 1 break operation at 2,000A. It meets stringent environmental and mechanical testing standards, including vibration, shock, corrosion, and humidity resistance as per SAE-J553 and IEC standards.
Its design makes it particularly suitable for installation in inaccessible locations where reliable protection is essential. The clear color coding of ratings corresponds to blade fuses of the same rating.
The 1626-2-20A has a nominal current rating of 20 A.
The maximum voltage rating is 14.5 V DC.
The operating temperature range is -40°C to +85°C.
The breaker uses an automatic reset actuator.
It is a single-pole circuit breaker.
The breaker is designed for holder mounting.
It can perform 300 operations at 2x rated current (40 A) for service short-circuit, and can break up to 150 A for 3 operations or 2,000 A for 1 operation.
