Thermal automotive Mini-CBE 1620-... Description Single pole, thermal miniaturised circuit breaker designed for automotive applications. Fits into fuse blocks designed to ISO 8820-3, Type F. Automatic reset (for DC 12 V only) and open circuit (modified reset to SAE) version optional. Open circuit version ensures contacts staying open as long as power is on. The circuit breaker will reset after the load is removed. Particularly suitable for installation in inaccessible locations. Current ratings correspond to those of blade fuses. Clear colour coding of the ratings: blade fuse and circuit breaker of the same colour have the same rating. 1 SAE type 1 SAE type 2 SAE type 3 Meets the requirements of SAE J553. US patent number: US 8,576,042,B2 Technical data Typical applications Protection of electrical systems of passenger cars, trucks, buses, watercraft, extra low voltage wiring systems.
