The E-T-A 1626-1-25A is a single pole, thermal miniaturized circuit breaker (Mini-CBE) designed for automotive applications. It fits into fuse blocks designed to ISO 8820-3, Type F. This model features an automatic reset function and is rated for a current of 25A and a maximum voltage of 14.5V DC.
Technical data indicates a fast characteristic curve for current ratings from 7.5A to 30A. The circuit breaker operates within an ambient temperature range of -40°C to +85°C. It offers 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 2,000A.
Environmental testing includes resistance to vibration (10g), shock (50g), corrosion (48 hrs in 5% salt mist), and humidity (240 hrs in 95% RH). The operating area has a degree of protection of IP40, while the terminal area is IP00.
Typical applications include the protection of electrical systems in passenger cars, trucks, buses, and watercraft, as well as extra-low voltage wiring systems. The current ratings correspond to those of blade fuses, with clear color coding for easy identification.
