Manufacturer:

Ziehl
Delivery date: 2 Weeks

Phase-sequence Relay, automatic change of wrong phase-sequence

104.5 CAD
+ -
Products specifications
Brand ZIEHL
Country of origin Germany
Rated supply voltage 3 AC 400 V, 50/60 Hz < 3 VA
Tolerance AC +10 % ... -20 %
Output relays 2 x 2 NO-contacts
Switching voltage max. AC 440 V

Phase-sequence relays DRR10 measure the sequence of the phases when being switched on and switch - if necessary - the rotation of the field by changing 2 phases. The integrated PTC-monitor protects the motor from overheating. Applications are especially machines and equipment, that is operated at variable locations e.g. at building sites. Pumps, compressors and vacuum cleaners always run correctly. No more search for faults or change of wiring necessary.

Overview of Function

*automatic change of wrong phase-sequence when connected falsely

*running backward of motors is avoided

*integrated PTC-protection for motor

*enable-input for direct switching on/off of the motor with DRR 10

*max. 3 x 12 A

*switch-on currents 30 A / max. 4 s / 60 A / max. 1 s

*higher currents with external contactors

*integrated protection for relay contacts

*integrated protection from over-temperature

*housing for mounting in fuse-boxes or switchgearcabinets, mounting height 55 mm
