How does a contactor differ from a relay
Did you know?
WebMar 17, 2024 · A contactor does not have a common between the phases and joins 2 poles together. A relay uses a common contact that connects to a neutral. Contactors are generally rated up to 1000v and relays are typically rated up to 250V. The load capacity of relays is mostly used for applications that carry 10A or less. WebJul 17, 2024 · Another difference between relays and contactors is in contact arrangements. Control relays are available with varying counts of N.O., N.C. and/or N.O./N.C. contacts to perform a wide range of duties, and relay can operate much faster than contactors. Contactors, on the other hand, are typically used to turn power on when energized.

If you are using it that way, the mechanical durability is the relevant number. cue banks courseWebUnlike relays, contactors are designed with features to control and suppress the arc produced when interrupting heavy motor currents. Contactors come in many forms with varying capacities and features. Unlike a circuit breaker, a contactor is not intended to interrupt a short circuit current. cue banks supply and demand
