Thermal Automotive Circuit Breaker 1610-...
Description
Miniaturised single pole press-to-reset cycling trip free thermal circuit
breaker designed for automotive fuse block installation.
Extends the benefits of circuit breaker performance and convenience
to applications which are cost critical. Colour-coded housing caps or
manual release buttons available.
Version 1616 is available especially for the automotive industry (current
ratings correspond to those of blade fuses).
US patent number:
US 6,590,489 B1 (1610-H2)
Typical applications
Extra low voltage wiring systems on all types of vehicles and marine craft.
