What is TeSys D contactor?

A TeSys D contactor offers you quick simple setup, while maintaining a compact size of 45 (9 to 38A) and 55 mm (40 to 65 A) as well as compliance with international standards. The contactor LC1D can be used with thermal overload relay LRD series for the Direct Online application.

What are Contactor Relays?

Summary. A contactor is a special type of relay used for switching an electrical circuit on or off. They are most commonly used with electric motors and lighting applications.

What is the difference between relays and contactors?

A contactor joins 2 poles together, without a common circuit between them, while a relay has a common contact that connects to a neutral position. Additionally, contactors are commonly rated for up to 1000V, while relays are usually rated to only 250V.

What is a line contactor?

A-Line contactors are mainly used for controlling 3-phase motors and for controlling power circuits corresponding to their operating characteristics up to 690 and even 1000 VAC and 440 VDC. All A-Line contactors can be assembled side by side. …

What are the two types of relay?

Types of Relays – A Thomas Buying Guide

• Relays are electrically operated switches.
• Electromechanical relays have an electromagnetic coil and a mechanical movable contact.
• Solid-state relays are solid-state electronic components that do not have any moving components, which increases their long-term reliability.

Why use a relay instead of a contactor?

Relays are used to control contacts of an electrical circuit due to a change of parameters or conditions in the same circuit or any other associated circuit. Contactors, on the other hand, are used to interrupt or establish connections in an electrical circuit repeatedly under different conditions.

How contactor is connected?

Contactor Connection Procedure Generally the magnetic coil of a contactor is designed to operate at a low voltage such as 230V AC, 110V AC, 24V DC, etc. So provide the power supply to the magnetic coil as per requirement. 2. Connect the main power supply terminal with the incoming terminals of the contactor.

When should a relay be used?

One of the most common situations that require the use of a relay occurs when an application needs to switch from high to low current (or vice versa) within the same circuit. For example, the temperature sensors that power HVAC units require levels of amperage that vastly exceed the capacity of their wiring.
