Description

Ordering information

Current ratings, typical voltage drop values and colour coding Technical data 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. Meets the requirements of SAE J553. US patent number: US 8,576,042,B2 Protection of electrical systems of passenger cars, trucks, buses, watercraft, extra low voltage wiring systems.

Free travel of the reset button must be ensured! Please ensure to push in the actuator smoothly and completely. Depending on the socket used and with the 30 A device carrying a full load, the temperatures at the terminals may rise above the allowed SAE value.

Thermal automotive Mini-CBE 1620-... www.e-t-a.de 2214 The time/current characteristic curve depends on the ambient temperature prevailing. In order to eliminate nuisance tripping, please multiply the circuit breaker current ratings by the derating factor shown below. See also section Technical information.
