Mcb By Rao Electronics

We are Exporting, Manufacturing and Supplying a wide array of MCBs that re designed to protect the cable downstream of the device against overloads and short circuits, preventing damage to cables and equipment.

MCBs are installed in modern consumer units, and are a convenient alternative to fuses as they can be reset without having to replace wire with a simple flick of a switch or button.

There are 3 MCB types, Type B, Type C and Type D, and the speed at which they trip depends upon the level of overload, and is usually determined by a thermal device within the MCB.

An MCB works by tripping when a circuit is overloaded or when a short circuit has occurred in the system, and has a current rating such as 6A, or 10A depending upon its intended use, i.e. for residential, commercial, industrial or public buildings.
