Description
Typical applications
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.
Breakers rated 7.5 A through 30 A have a fast characteristic curve and
only hold 70 % of their rated current continuously.
US patent number: US 8,576,042,B2

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.
All dimensions without tolerances are for reference only. In the interest of improved design,
performance and cost effectiveness the right to make changes in these specifications without
notice is reserved. Product markings may not be exactly as the ordering codes. Errors and
omissions excepted.
