Circuit Breaker Bases & Accessories

Circuit protection is vital to any electrical system and circuit breakers and fuses are the main components to provide this protection. When a short circuit or overload occurs, breakers and fuses are designed to disconnect the current, preventing irreparable damage.

Miniature circuit breakers are electromechanical, temperature-sensitive devices contained within a plastic casing with an on/off switch, which makes them very easy to use. These breakers are mainly designed for low-energy circuits and automatically reset when the overcurrent is removed and the temperature returns to a safe level. Miniature circuit breakers have a current rating less than 100 amps and have an interrupting rating less than 18,000 amps. They come in different types according to their tripping or overcurrent characteristics. The three main types, B, C and D can be selected based on their response to different electrical surges in different settings.

Molded circuit breakers are electromechanical, temperature-sensitive devices contained within a plastic casing with an on/off switch, which makes them very easy to use. These breakers are mainly designed for high-power equipment due to its better capacity and automatically reset when the overcurrent is removed and the temperature returns to a safe level. Molded case circuit breakers are similar to miniature circuit breakers (MCB) in methodology, however the main difference between the two is in the capacity. MCBs current rating is under 100 amps with an interrupting rating under 18,000 amps while MCCBs current rating is 1,000 amps with an adjustable trip function that allows an interrupting range from 10,000 amps to 200,000 amps.
