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.
Features
- Star-delta relay according to IEC/DIN EN 61812-1
- Time delay up to 100 s
- Repeat accuracy < ± 0.5 %
- Wire connection: Also 2 x 1.5 mm2 stranded ferruled, or 2 x 2.5 mm2 solid DIN 46228-1/-2/-3/-4
- As option with pluggable terminal blocks for easy exchange of devices- With screw terminals- Or with cage clamp terminals
- Width 22.5 mm
