WebWhat is a relay, its function, types and relay wiring A relay is an electrical component that can control the flow of electricity in a circuit. The relay can be energized at one time and de-energized at another. This allows the relay to open and close and interrupt and reestablish electric circuits. WebGeneral-purpose relays come in three duty ranges; light (two amperes of current or less), medium (two to ten amperes), and heavy or power type (15 or more amperes). They …

A contactor is an electrically-controlled switch used for switching an electrical power circuit. A contactor is typically controlled by a circuit which has a much lower power level than the switched circuit, such as a 24-volt coil electromagnet controlling a 230-volt motor switch. Unlike general-purpose relays, contactors are … See more A contactor has three components: • The contacts are the current-carrying part of the contactor. This includes power contacts, auxiliary contacts, and contact springs. Contact material is chosen for high electrical … See more Contactors are rated by designed load current per contact (pole), maximum fault withstand current, duty cycle, design life expectancy, voltage, and coil voltage. A general purpose … See more Lighting control Contactors are often used to provide central control of large lighting installations, such as an office building or retail building. To … See more In addition to their current ratings and rating for motor circuit control, contactors often have other construction details not found in relays. Unlike lower-powered relays, contactors … See more When current passes through the electromagnet, a magnetic field is produced, which attracts the moving core of the contactor. The electromagnet coil draws more current … See more Without adequate contact protection, the occurrence of electric current arcing causes significant degradation of the contacts, which suffer significant damage. An electrical arc occurs between the two contact points (electrodes) when they transition from a … See more When a series of contactors is to be operated in sequence, this may be done by a camshaft instead of by individual electromagnets.
