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.

Caution:  
It is good practice to switch off the vehicle’s ignition system before  
manually releasing or re-setting the circuit breaker. 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.
