How the contactor operates operating principle of a contactor.

Electrical contactor working principle pdf.

The current passing through the contactor excites the electromagnet. 1 what is a contactor in electrical terms. كيف يعمل قواطع contactors are electrically controlled switching devices used for switching of e. Working of contactor as contactors are used for high current load applications they are designed to control and reduce the arc produced when the heavy motor currents are interrupted.

In most cases the contactors are connected in normally open contacts and the relays are connected as normally closed contacts. Low voltage contactor is an electrically controlled switch used for switching an electrical power circuit similar to a relay except with higher current ratings. A contactor is an electrically controlled switch used for switching an electrical power circuit. Contacts and n o contacts can never be closed simultaneously.

The maintenance of contactor is easy while in most of the conditions the relay cannot repair. Magnetic contactor working principle in english how mc works with animation earth bondhon a contactor is an electrically controlled switch relay used f. This video explains the principle of operation of contactors. The excited electromagnet produces a magnetic field causing the contactor core to move the armature.

In process industries a contactor is a vessel where two streams interact for example air and liquid. At the same time it is necessary to ensure that the contact gaps are at least 0 5 mm over the lifespan even when defective e g. A normally closed nc contact completes the circuit between the fixed contacts and the moving contacts. A contactor is controlled by a circuit which has a much lower power level than the switched circuit.

Contactor relays dil two contactor relay series are available as. A contactor is typically controlled by a. Other than the low current contacts they are also setup with normally open contacts. The size of the contactor is large compared to the size of the relay.

The contactor relays diler and dila fulfil this requirement. 2 operating principle of a contactor 3 functions of a contactor 4 types of contactors 4 1 magnetic contactors 4 2 knife blade switch 4 3 manual controller 5 differences between a contactor and a relay.
