Contactor شرح

A contactor is an electrically-controlled switch used for switching an electrical power circuit. Definite purpose magnetic contactors are ideal for many HVAC and cooling applications, while lighting magnetic contactors are for use in switching electrical power circuits. Specialty contactors include mercury displacement models suitable for heating and motor loads.

Large electric motors can be protected from overcurrent damage through the use of overload heaters and overload contacts. A contactor joins poles together, without a common circuit between them, while a relay has a common contact that connects to a neutral position. The contactor relay contacts themselves constitute a considerable safety feature.

By design and construction they ensure potential isolation between the actuating circuit and the operating circuit, in the de-energized state, between the contact input and output. All DIL contactor relays have double-break contacts. Check us out first for all your industrial electrical component needs! We Have Almost Everything On eBay. Prevent expensive damage to industrial machinery with heavy-duty magnetic contactors from Grainger.

The correct contactor type and capacity bridges the gap between direct power sources and high-load electrical lights, heaters and motors, balancing out changes in electrical frequency and cutting the current in the event of a malfunction or overload. The same is true when someone uses a normal operation motor contactor for motor jogging duty. We provide energy-efficient solutions that help our customers effectively manage electrical, hydraulic and mechanical power more efficiently, safely and sustainably.

Subcontractor vs Contractor: Understanding the Difference This resource article talks about some of the differences between contractors and subcontractors who work in the field of construction. Contactors have specific designs for specific purposes. Although these terms are sometimes used interchangeably, it is important to understand the few key differences between the two roles and how they work.

The function of the contactor is to make and break all power supply. They are currently utilized in a variety of industrial electric equipment. These include air conditioning, heating, refrigeration, food processing, agricultural plus numerous other applications. General contractors are the backbone for any home improvement or remodel job.

They typically will pull permits, hire subcontractors, and outline the project to keep costs within budget. With its launch of the complete AF contactor range, ABB sets a new benchmark in motor control and protection. The long-term reliability of this process is evident in the thousands of units in operation for more than years with Evoqua as the original equipment manufacturer (OEM). LamdLyrics 306views.

Your air conditioner’s contactor and capacitor work together to help power your air conditioner’s fan and compressor whenever your thermostat calls for cool (the capacitor and contactor in your heat pump work the same way). It’s a standard magnetic relay, meaning low voltage flows through a coil inside the contactor to creates a magnetic fiel which then pulls down a piece. Alternating current (AC) and direct current (DC) contactors are found in many industrial motors, including many automobiles. Thermal overload relays are economic electromechanical protection devices for the main circuit. They offer reliable protection for motors in the event of overload or phase failure.

The thermal overload relay can make up a compact starting solution together with contactors. Relay is device having typically an electromagnet controlled contacts, actuated by electric signals in one circuit to control current or supply in another circuit.

So it usually has a magnet coil, few contacts which may be one or more pairs of con.
