Miniature Circuit Breakers

Capital Electric Supply offers the best miniature circuit breakers that contractors trust, so they can do what they do best without worrying about the basics. With A-B circuit breakers of just 1/2″ width and under 4″ length, these miniature circuit breakers are perfect for working in tight spaces and small enclosures, or 12-24A applications. Whereas fuses need to be thrown out after an overload, MCBs provide long-term circuit protection and noticeably reduce installation time. These are designed and tested to meet ANSI standards, are CSA-certified and come under warranty.
