|
The relay closes when the proper sequence (ABC) is applied, but will remain open if any two phases are reversed. If reverse phasing occurs during operating, the relay also de-energizes. The Model 253 has a special industrial-grade relay designed for low power consumption. The ABC indicator will be illuminated when the proper phase rotation sequence is applied.
