FR-02 Phase Sequence

FR-02 FQ-01 SERIES PT-01
FR-02 is an electronic relay, which monitors the L1,L2,L3
phase sequence.
FR-02 Phase Sequence Relay is developed to check the
phase sequence. If the nput
FR-02 phase relay is used in pumping systems, air compressors
and elevators. FR-02 is suggested to be used in such systems where,
reverse rotation of motors can cause damage to people or systems.
i R, S and T phases are in correct
phase sequence, the light on the front panel turns ON and the
output relay swit
