Phase Sequence
FR-02
Summary
FR-02 is an electronic relay for monitoring phase sequence of L1, L2 and L3. FR-02 phase sequence relay is used to check phase sequence. If the phase sequence of R, S and T input is correct, the front panel lights up and the output relay turns on. If the phase sequence is wrong, the lamp is turned off and the output relay is turned off. FR-02 phase sequence relay is used in pump system, air compressor and elevator. FR-02 is recommended for systems where motor reverse rotation can lead to injury or system damage. |
