A contactor is typically controlled by a.

Electrical contactor working principle pdf.

The size of the contactor is large compared to the size of the relay. A normally closed nc contact completes the circuit between the fixed contacts and the moving contacts. In most cases the contactors are connected in normally open contacts and the relays are connected as normally closed contacts. A contactor is controlled by a circuit which has a much lower power level than the switched circuit.

This video explains the principle of operation of contactors. 1 what is a contactor in electrical terms. The contactor relays diler and dila fulfil this requirement. In semiconductor testing contactors can also be referred to as the specialized socket that connects the device under test.

The current passing through the contactor excites the electromagnet. 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. كيف يعمل قواطع contactors are electrically controlled switching devices used for switching of e.

The excited electromagnet produces a magnetic field causing the contactor core to move the armature. Other than the low current contacts they are also setup with normally open contacts. 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. In process industries a contactor is a vessel where two streams interact for example air and liquid.

The maintenance of contactor is easy while in most of the conditions the relay cannot repair. 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. Magnetic contactor working principle in english how mc works with animation earth bondhon a contactor is an electrically controlled switch relay used f. Contacts and n o contacts can never be closed simultaneously.

When a contact is welded. Contactor relays dil two contactor relay series are available as.
