MCB Changeover Connection:

This diagram shows how to connect MCB Changeover Connection. In this circuit diagram, we use a DP MCB ( Double Pole Miniature Circuit Breaker), an MCB changeover, a single-phase energy meter, and a power generator. First, we need to input power in the energy meter from the grid line, then output power from the energy meter to input DP MCB and output power to MCB changeover and generator. If you want to see more clear connection please check our youtube video below the post.

Components used to make the MCB Changeover Connection:

01. Single Phase Energy Meter

Single Phase Energy Meter
Fig 2: Single Phase Energy Meter
The measuring device with the help of which the electric power or energy of a circuit is measured is called Energy Meter (Energy Meter). Also called a watt-hour or kilowatt-hour meter. For home appliances, we used a single-phase energy meter. The single-phase energy meter is directly connected between the line and the load. Both coils produce their magnetic fields, when the meter is connected to the supply line, and the load. Energy meters are used in homes and in industrial applications where we want to found that how much energy is being consumed by home appliances and electrical equipment.

02. MCB Changeover

MCB Changeover
Fig 3: MCB Changeover
Changeover is a medium of line transfer used in industry. Now if I make the change over the system automatically then this system is called auto change over the system is called ATS system. From this change over first power supplied from REB or PDB is supplied to the industry to run the machine. Now if for some reason the power supply When stops, the generator is run and the changeover is turned and power is supplied to the machine. Now if this power supply is done manually like this and if it is done manually by any person then it is a manual changeover.

03. DP MCB

Fig 4: DP MCB
Double pole MCB can control two wires. This circuit breaker is generally used in single-phase electric lines. Double pole MCB circuit breaker input has two wires supply two wires and an output. In a single-phase line, A double-pole MCB circuit breaker is used to give good production. This circuit breaker is provided through phase and neutral circuit breaker, it is very safe. This circuit breaker is preferred for home appliances. A DP MCB usually trips for 2 reasons 1. Overload 2. Short circuit.

04. Power Generator

Power Generator
Fig 5: Power Generator
The Power Generator Is a Device That Converts Motive Power (Mechanical Energy) or Fuel-Based Power (Chemical Energy) Into Electric Power for Use in an External Circuit. In Addition to Electromechanical Designs, Photo Voltaic, And Fuel Cell-Powered Generators Utilize Solar Power and Hydrogen-Based Fuels, Respectively, to Generate Electrical Output. The Reverse Conversion of Electrical Energy Into Mechanical Energy is Done by an Electric Motor, And Motors, And Generators Have Many Similarities. Many Motors can be Mechanically Driven to Generate Electricity; Frequently They Make Acceptable Manual Generators.

Frequently Asked Questions

What is the function of changeover in MCB?

MCB Changeover switch finds wide applications in industries as well as in domestic areas especially in Individual Bungalow(IB) for use in low voltage distribution circuits diagram wherever continuity of supply is necessary. It is used for switching to an alternate source of supply from the main supply or vice–versa.

Can we use MCB as a switch?

Using an MCB in place of the switch for regular on/off operations is not ideal. While the MCB may be capable of interrupting the electrical flow when switched off, it is not designed for frequent switching operations or may not provide a convenient user experience.

What is MCB 63A?

TOMC5-63 3P 63A MCB switch is applied at direct current circuit diagram system, with rated operation voltage DC 220V, rated current flow up to 63A, to protect against overload and short circuit, or also for infrequent changeover for the lines.

Which is better MCB or switch?

MCB could be safely closed on to a fault whereas, it is not allowed in case of the switch with a fuse as it may flashover. MCB has limited fault of the rating - typically 10kA whereas, fuses are available with fault ratings as high as 100kA.

Which MCB is best for?

The best-suited type of MCB for domestic appliances, where the current flow load is medium, is type C. Type C MCB trips off when the flow of current flow is 5-10 times more than normal. Type D MCB has a high resistance as they can withstand up to 10-20 times the current flow rate.
