MCBs
Our selection of MCB circuit breakers offers exceptional durability, fast response times and easy installation, ensuring maximum efficiency and peace of mind. Whether you need a single-pole, double-pole, or three-phase MCB, we have the right solution to meet your electrical protection needs.
What is an MCB Circuit Breaker?
A miniature circuit breaker is an essential piece of circuit protection that automatically cuts power in the event of an overload or short circuit, preventing damage to electrical systems and reducing fire risks.
MCBs work by continuously monitoring the electrical current flowing through a circuit. If the current exceeds the safe limit due to excessive load or a fault, the MCB circuit breaker automatically disconnects the power supply, preventing overheating, equipment damage, and potential fire hazards.
Available in various types and ratings, MCBs are used across residential, commercial and industrial applications. They come in different configurations, including single-pole, double-pole, triple-pole and four-pole models, allowing for precise protection of different electrical setups.
Miniature Circuit Breaker Types
Choosing the right MCB circuit breaker depends on the application and the type of electrical load it protects.
MCBs come in single-pole, double-pole, triple-pole and four-pole configurations, designed to safeguard single-phase and three-phase circuits. They are also classified by tripping characteristics, which determine how quickly they respond to faults.
Type B MCBs are ideal for homes and light commercial use, tripping at 3 to 5 times the rated current. Type C MCBs handle moderate inrush currents, making them suitable for industrial lighting and motor circuits. Type D MCBs trip at 10 to 20 times the rated current, providing protection for high-inrush equipment like transformers and heavy machinery.
