3 phase motor ampere meter calculation diagram:

This diagram shows how to make 3 phase motor ampere meter calculation diagram. In this circuit, we use FP MCB ( Four Pole Minature Circuit Breaker ), a magnetic contactor, an overload, an ampere meter, and a selector switch. First, we need to connect FP MCB with the power source, then connect the magnetic contactor and overload with the FP MCB, then connect the amperemeter and selector switch with the contactor.

Components used to make the 3 phase motor ampere meter calculation diagram:

01. FP MCB:

4 pole MCCB for 4-Wires Connections, the one additional 4’th pole for Neutral Wire Connection so that between Neutral and any of the other three will supply. In 4-Pole MCCB the Neutral Pole is also having Protective release as in the Phase Poles. Three Phase Supply with Neutral. TPN means triple pole TP + Neutral which is 3 – phases and Neutral, but the Protection is given for Three Phases only and in 4 poles MCB Protection is given to all 3-Phases as well as Neutral. In the case of a 4-pole MCB, the Purpose is not to protect the Neutral but it is rather to Isolate the Neutral.

02. Ammeter:

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 an ammeter. So it can be said that the device which measures the flow of current in an ampere unit is an ammeter. Electric current is the flow of electrons whose unit is an ammeter. So it can be said that the device which measures the flow of current in an ampere unit is an 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.

03. Selector Switch:

A Mechanical Switch That can be rotated Left, right, or center to open or close the electrical contacts is known as a Selector switch. The Main Function of This Selector Switch is to Control Devices and also to Switch Between a Minimum of 2 or Above Electrical Circuits. The Perfect Used for Selector Switch is When Used for Controlling an Output of a Device. We know that a Selector switch is Used to control the electrical current flow in a Circuit it can also be used to both Initiate and inhibit the Current Flow.

04. Magnetic Contactor:

A magnetic contactor is an electromagnetic switching device. It is generally used for controlling three-phase motors. The operation of a magnetic contactor is similar to that of a relay, but a relay is used for low-power or low-voltage connections, and a magnetic contactor is used for high-power or high-voltage connections. As soon as the supply is applied to the magnetic contactor coil, its normally open contacts are closed and normally closed contacts are opened and the associated devices are also operated. This is how a magnetic contactor works.

05. Overload Relay:

Overload Protection is Protection Against a Running Overcurrent That Would Cause Overheating of The Protected Equipment. Hence, An Overload is Also a Type of Overcurrent. Overload Protection Typically Operates on an Inverse Time curve where the Tripping Time Becomes less as the Current Increases. This Overload Protector is an Essential Component for Many Sockets. The Top-Quality Overload Protector can Effectively Protect Electrical Products from Power Surges.
