DESCRIPTION

The Model 253 Reverse Phase Relay is a solid-state

sensing device designed for installation in equipment

using 3-phase power.

desirable to have a contact closure indicating that the

proper phase rotation sequence has been applied.

The relay closes when the proper sequence (A B C) is

applied, but will remain open if any two phases are

reversed. If reverse phasing occurs during operation,

the relay also de-energizes.

The Model 253 has a special industrial grade relay

designed for low power consumption.

indicator will be illuminated when the proper phase

rotation sequence is applied.
