3 Phase Voltage Monitoring Relay

Control for connection of moving equipment(site equipment,agricultural equipment,refrigerated trucks). Control for the protection of persons and equipment against the consequences of reverse running. Normal/emergency power supply switching. Protection against the risk of a driving load(phase failure).

GEYA 3 Phase Voltage Monitoring Relay is designed for protecting three-phase voltage equipment from impermissible circuit voltage surges, phase breaks, phase imbalance, phase adherence, and phase sequence violation.

The relays are effectively utilized for protection of refrigerating, compressor, air conditioning and other equipment with electric motor loads.

GEYA 3 Phase Voltage Monitoring relay is used in devices that require continuous monitoring of circuit voltage quality, availability, and phase content like automatic transfer schemes.

All voltage monitoring relays have the resetting ratio of about 5V. the effective range of relays is 30-150% of rated voltage.

GEYA 3 Phase Voltage Monitoring Relay provide for automatic load energizing after voltage parameters recovery within predetermined time relay.

The relays are compact in sizes and weight. All relays are mounted unto standard DIN-rail.
