The PCP Series Three-Phase Monitor Relays continuously monitor all voltages to protect motors and equipment from expensive damage due to phase reversal. These products have an isolated relay output that is only energized if the three phases are in the proper A-B-C sequence. The relay output will remain open if any two phases are reversed.

Phase Reversal Relays should be used in applications where motor direction is critical or sequence detection is required by Code. NOTE: these products provide protection against phase reversal only. If a product with more than phase reversal protection is required, see the Reference Guide at the beginning of this catalog section to select the correct product.

The PCP Series is a true universal product, with two units that work on a wide variety of line-line voltages without any adjustment to cover more global applications. They utilize an industry-standard 8 pin octal socket.

Operation:
When the proper three-phase line voltage is applied to the unit and the phase sequence (rotation) is correct, the relay is energized after the Restart Delay is completed. An out-of-sequence condition will prevent the relay from energizing on start-up or de-energize the relay after a delay if it occurs when energized. Re-energization is automatic upon correction of the fault condition. A bi-color status LED indicates normal condition and also provides specific fault indication to simplify troubleshooting.

 

Features

• Protects against phase reversal only
• Universal voltage range of 190-500V or 460-600V—greater range that covers more global applications
• Full fault indication on top of unit for easy troubleshooting
• 10A SPDT output contacts
