MCBs
What is the Function of MCB?
By automatically cutting off the power, circuit breakers like MCBs help protect electrical systems, appliances and other equipment from damage. Circuit breakers, including RCCBs and RCBOs, also protect users from dangerous electric shocks.
What are the Different Types of MCBs?
There are different types of MCB based on their usage in domestic, commercial and industrial settings. Type B trips between 3 and 5 times its load current. Type C will trip between 5 and 10 times, and Type D between 10 and 20. The latter is best suited for industrial applications with high inductive loads.
At Toolstation, we stock many MCBs and accessories from leading brands like Contactum, Protek, Wylex, Crabtree Loadstar and Axiom. This includes top-quality MCBs constructed with high integrity metal for durability.
