Thermal Automotive Circuit Breaker 1170-...
Description
Compact single pole thermal circuit breaker with push-to-reset, tease
free, trip free, snap action mechanism and separate (colour coded)
manual release. Combining full feature circuit breaker protection and
convenience with low cost of ownership benefits. Fitted with blade
terminals for plug-in mounting.
Type III to SAE J 553.
Version 1176 is available especially for the automotive industry (current
ratings correspond to those of blade fuses).
Typical applications
Extra low voltage wiring systems on all types of vehicles and marine
craft.
