Time Mark Corp. Model 253 Reverse Phase Relay, SPDT, Socket Mount

The Time Mark 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.

Features:

• Socket-mounted
• Senses phase reversal
• Low power consumption
• UL Recognized; CSA Certified
