Magnetic contactor wiring:

This diagram shows how to make Magnetic contactor wiring. In this circuit, we use a TP MCB ( Tripple Pole Miniature Circuit Breaker ), a DP MCB ( Double Poel Miniature Circuit Breaker), and a magnetic contactor. First, we need to connect the DP MCB with the power source, then connect the TP MCB with the power source, then connect the contactor with the TP MCB and the DP MCB. Now this circuit is ready for use. If you want to know more please stay with our website.

Components used to make the Magnetic contactor wiring:

01. DP MCB:

DP MCB In 2 Pole MCB, switching & protection is affected in phases and the neutral. A Double Pole or DP Switch is a Switch that Controls 2 Circuits at the same time. In terms of Residential Switching, this Normally means it Switches the live and Neutral at the same time. In Layperson Terms, Double Pole switches or DP Switches are Exclusively Designed to Control 2 Different Electrical Circuits at the same time, which allows the Appliances to Isolate safely and reliably. Fan or light Combinations and Medical Equipment are some of the many applications for DP Electrical Switches and Electrical components.

02. TP MCB:

The full meaning of MCB is Miniature Circuit Breaker for TP MCB. MCB is an electromagnetic switch or device. If for any reason a short circuit occurs in the supply line or load line (line to line or line to neutral) or in case of overload MCB. the MCB automatically trips and disconnects the main line circuit or household power supply Connection. TP MCB In 3 Pole MCB, Switching & Protection is affected in only 3-Phases and the Neutral is not part of the MCB. 3 pole MCB signifies the Connection of Three Wires for a 3-Phase system Red-Yellow-Blue Phase. 3-Phase Supply Only Without Neutral.

03. Magnetic Contactor:

A magnetic contactor is an electromagnetic switching device. It is generally used for controlling 3-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.

Frequently asked questions

What is the magnetic contactor?

A magnetic contactor is an electrical switching device. It is used for switching an electrical circuit diagram on or off. It is a special type of relay but there is a basic for the difference between the contactor and a relay.

What is a 3-phase magnetic contactor?

For the control of 3-phase motors, magnetic contactors are used to open and close the power supply contacts in line with the motor. This allows for the separation of the control circuit diagram and the power circuit, providing greater safety for the operator and ease or convenience of wiring for the installer.

What is the principle of contactor?

Operating Principle of a Contactor, The current supply passing through the contactor excites the electromagnet. The excitedness of an electromagnet produces a magnetic field, causing the contactor core to move the armature. A normally closed (NC) contact completes the circuit diagram between the fixed contacts and the moving contacts.

Why is a contactor important?

While there are differences, the main purpose of a contactor remains to manage or break high current load. Their capacity is huge, where an average contractor could break currents from a single volt to thousands of volts. For example, a contractor can handle currents of over 5000 amperes and power supply above 100kW.

What is the voltage of a contactor coil?

The current supply input to the contactor coil may be DC or AC (available in different of voltage ranges between 12VAC or 12VDC to 690VAC or 440VDC). A small amount of power supply is used up by the contactor coil during its operation.
