125A HIGH-BREAKING MINIATURE AC CIRCUIT BREAKER
An AC miniature circuit breaker (MCB) is a crucial component of electrical systems, designed to protect electrical circuits from damage due to overcurrents or short circuits. They are compact, easy to install, and provide reliable protection for various applications, including residential, commercial, and industrial settings.
AC MCBs are essential for ensuring the safety of your electrical appliances and preventing damage to the wiring. They automatically cut off power to the circuit when a fault occurs, thus avoiding hazards like electrical fires, equipment damage, or electrocution.
Types Of Ac Mcbs
There are four primary types of AC MCBs, classified based on the number of poles they protect:
Single Pole Mcb
A single-pole MCB provides protection for one phase or live wire. It is commonly used in residential settings where only one live wire requires protection.
Double Pole Mcb
Double-pole MCBs protect both the live and neutral wires in a single-phase electrical system. These are typically used in residential and commercial settings where it’s necessary to disconnect both wires for safety reasons.
Triple Pole Mcb
Triple-pole MCBs are designed for three-phase electrical systems and protect all three live wires. They are widely used in industrial and commercial applications.
Four Pole Mcb
A four-pole MCB protects three live wires and one neutral wire in a three-phase electrical system. They are primarily used in applications where separate neutral wire protection is required.
