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.

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.
