Molded case circuit breaker testing encompasses dealing with a wide range of ampacities as breakers are specifically designed to handle particular loads and applications. The trip characteristics therefore vary typically from ampacities as low as five amperes and reaching the high ends of 2000 to 3000 amperes. The image shown here is a smaller benchtop high current test set, the Multi-Amp MS2,which we use for testing molded case circuit breakers ranging from five to sixty amperes. All tested/requalified molded case circuit breakers come with our standard 1 year repair/replacement warranty.
