Coil current?

Given the supply voltage range what is the operating and holding current for the coil? I assume: A1 is switched line A2 is switching circuit neutral 1 line supply 3 neutral supply 2 line load 4 neutral load Correct?
Asked by: STH001

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.

does the contactor come with an N/O auxillary contact

Asked by: kendo669
Hi kendo669. The contactor is normally open if there is no power on the control line, it closes when power is supplied.
