Schneider Electric RE10RQM7N Harmony Timer Relay Star-Delta 2-120s 240V AC 1NO+1NO Timer Relay

The Schneider Electric RE10RQM7N is a Harmony modular timing relay with the Q (star-delta) function, switching two 5 A normally-open outputs from a shared common after a 2 to 120 second delay on a 240 V AC supply. It is built for star-delta motor starting sequences where the transition timing must be fixed and repeatable.

Selection Notes

The split common wiring of the 1 NO + 1 NO output pair lets this relay drive the star contactor on one output and the delta contactor on the other from a single timing element, with the Q function opening one output before closing the other to avoid a star/delta short circuit during transition. The 2-120 s range covers typical motor run-up times for medium induction motors; where a wider 0.1 s-30 h range is needed for non-motor timing duties, the single-contact RE10RAMUN or RE10RCMUN in the same housing are the sibling parts to specify instead.
