How do I reduce case cracks and breakage in surface mount devices?
Unlike competitive devices that are made from thermoset material, MP’ s Hi-Amp Circuit Breakers (Series 17, 18 & 19) are molded using high temperature thermoplastic that is very resistant to cracking and breaking.
How do you reduce terminal corrosion in harsh environments?
Many MP J553 qualified circuit breakers automatically come with stainless steel terminals and hardware.
How do you identify the rating of Short-Stop Circuit Breakers?
