Description
The Model 253 Reverse Phase
Relay is a solid-state sensing device designed for installation
in equipment using 3-phase power. This unit is used where
it is desirable to have a contact closure indicating that
the proper phase rotation sequence has been applied.
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.
