Miniature Circuit Breakers (MCBs) are a vital element for circuit protection in f electrical systems. They protect circuits from overloads and short circuits, preventing damage to equipment, and potentially dangerous electrical fires or injury. Breakers are automatic switches that interrupt the flow of electricity by tripping quickly and shutting off power to the affected circuit before any damage from an overload or short circuit occurs. Noark’s MCBs offer excellent quality in a compact size and are backed with our standard 5-year warranty which makes them ideal for use in a wide range of applications.
