The MCCB consists of a bimetallic sheet that expands and contracts when the temperature of the MCCB changes. Due to overload, the bimetallic strip will start to bend and eventually, it will trip if more current flows in the circuit than the predetermined current. The trip mechanism opens the breaker. MCCB stands for Molded Case Circuit Breaker. It is another type of electrical protection device that is used when the load current exceeds the limit of a miniature circuit breaker. The MCCB provides Protection against Overload, and Short Circuit Faults and is also used for Switching the Circuits.

Ammeter, an instrument, with the help of which the flow of electricity can be measured directly in electrical units, amperes. It is a galvanometer with very low resistance. As a result, the entire current flows through the meter coil. Current is measured with ammeter. So it can be said that the device which measures the flow of current in ampere unit is ammeter. Electric current is the flow of electrons whose unit is ammeter. So it can be said that the device which measures the flow of current in ampere unit is ammeter. An ideal ammeter has no internal resistance. But in reality the ammeter has little internal resistance. The range of the ammeter depends on this resistance.

An indicator lamp just Sounds Technical, Sometimes it’s called a “Supervisory” light Indicator. Indicator lights are amber in color and can be located at the Front, the Rear, and Sometimes at the Side of the car on both the left And Right-hand sides. The Common colors used by Indicator lamps are red, yellow, blue, white, and green. A Panel Indicator Lamp Generally has up to 5 Differently Colored Segments to Indicate Various Conditions on the Machine or Process
