Circuit breaker, automatic. No mount, metal. 40A

No mount tabs, with metal housing. Automatic re-set. With 10-32" (4.76mm in diameter) threaded poles with nuts included. This is an automatic resetting circuit breaker, the fuse system as used in many pre-2000 H-D models for decades. When triggered it will, after some time, automatically re-set itself. Great for use in many stock or custom applications.
