Description:
The RD6 ANT RD6-W series 3 phase sequence voltage monitoring relay are Ideal for Monitoring 3-phase Power Supplies for Industrial Facilities and Equipment, and for incorrect phase sequence, phase failure and phase imbalance on systems up to 500V.Phase failure.It is used to ensure the sequence is correct when connecting 3 phase loads. With an incorrect phase sequence the relay will start to de-energise, preventing the starting of incorrectly connected machinery. The relay will also trip if there is a phase loss and can therefore be used as a phase failure relay.Phase Sequence Relay controls the order of 3 phases feeding motors. If R,S and T phases are in correct order, ON LED on the front panel is turned on. If the phase order is wrong, ON LED is turned off and the output relay is switched to OFF. Phase sequence relay is used to protect 3 phase motors in systems of air compressors, elevator and etc. FR-02 is recommended to use in applications where unexpected false rotating direction of motors can cause injury to person and damage the property.
Phase Imbalance
