Star-Delta-Timer
MK 7853N

The MK 7853N is a static star-delta-timer with 2 separate output relays. As soon as the operating voltage is applied, relay 1 will be energized and falls back after time delay. After elapse of the contact changeover time, the second relay switches on and remains in active position, as long as the star-delta-timer is energized.

Advantages
. Limiting the starting current
. Reduced power consumption of the three-phase motor during the start-up phase
. Prevention of tripping of overcurrent protection devices
