Tracing a short circuit can be a very time consuming exercise. This Short Circuit Diagnostic Kit provides a solution in the form of a set of circuit breaker fuses, designed to fit in place of the traditional fuse. The circuit breaker will safely break the circuit when an overload is detected, just like a conventional fuse, but it is also manually resettable, allowing the technician to reset the circuit breaker fuse to run their tests as many times as they need. Contents includes: 7 standard blade manually resettable circuit breaker fuses & 7 mini blade manually resettable circuit breaker fuses.Fuse ranges: 5A, 7.5A, 10A, 15A, 20A, 25A, 30A. Supplied with two, 300mm (12”) extension loop leads for better access for use with both blade sizes. Manufactured to: SAE J553 (TYPE I & II & III) Circuit Breakers.
