ABB System Pro M Compact System Pro M Compact Miniature Circuit Breaker, 1-Pole, 10A, Type B, 253V ac AC, 72 V dc DC, 6

Use this single-pole MCB from ABB to protect people and equipment from the harmful effects of overvoltage. The type-B unit trips instantly to break a single-phase circuit whenever the current supplied exceeds 3 to 5 times its rated current of 10A. As its sensitivity helps ensure prompt breaking whenever the slightest overcurrent occurs, this is a safe choice for use in residential settings where surges are small. Because MCBs work like switches, you simply reset this unit manually after a fault so it can continue to protect your circuit and connected devices.

• Current limiting, so it restricts how much harmful current can pass through during a fault for user safety

• Light commercial spaces

MCBs use an internal strip made of two types of metal. The metals bend at different temperatures when heated by overcurrent, which deforms the strip and triggers a latch. This breaks the circuit to ensure safety for equipment and users.
