Replacing a faulty 40amp 2 pole VAC 240 contactor rated AC3. Your contactor specs say rated AC7a & AC7b, so would it be suitable to replace a 40 amp contactor rated AC3?

Asked by: aviator42long
Hi aviator42long, Contactor ratings are used to signify what they are designed to handle:- AC-3 rated contactors are generally preferred for the starting of Squirrel-cage motors and switching off motors during the running time, which means the contactor can withstand high currents continuously. E.g.: lifts / elevators, fans, etc. AC-7a rated contactors are generally for small Inductive loads in households such as TVs, mixers, etc. AC-7b rated contactors are generally for rotating machines in households such as fans, central vacuum cleaners, washing machines etc. So the suitability of our contactor will depend on the duty to which you intend to put it.

Can this be driven from a 24v supply?

Asked by: toomanytools
Hi toomanytools, The spec for the control connections on this contactor is for a standard UK 220-250V AC power level, so no a 24V (presumably DC) power level would not be suitable.

Can two of these contactors have a mechanical interconnect so only one of the two contactors can be open at any one time?

Many contactors allow the switches to be connected by a small pin so as one is open the other has to be closed.
Asked by: HoneyJukes
Hi HoneyJukes, Unfortunately not, the contactors are manufactures as NO across the board with no way to alter them to being NC mechanically or linking them together to operate alternately.

Can two of these contactors be mechanically linked so that one is NO and the other is NC as I wish to build my own generator/grid ATS with time delay actuators.

I intend to connect it to a generic off the shelf ATS unit so that when grid power fails the grid contactor immediately goes open and after 15 second delay the generator contactor closes.
