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

Protection of electrical systems of passenger cars, trucks, buses,

watercraft, extra low voltage wiring systems.

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.
