Voltage relay CP-721-1 (CP-721-63A) (single-phase; digital display; supply voltage 50-450V contact 1NO 63A built-in timer fault logging in memory current voltage display) (analog of UZM) F&F EA04.009.013 Evroavtomatika F&F

"CP" series voltage relay DIN-rail mounting. Designed to protect electrical installations, electrical appliances, and other electronic equipment from overvoltage or undervoltage, neutral wire breakage, recording extreme voltage values, as well as the type of accident occurred, and monitoring the voltage level in the single-phase AC supply network. Protection is carried out by disconnecting the load from the power supply. The relay contact is closed and the load is switched on if the monitored voltage is within the set range. The range (upper and lower values) is set using buttons on the front panel. Automatic reconnection of the relay (after disconnection) occurs after a set time once the mains voltage is restored. In case of restoration after a voltage absence, the automatic reclosure (APR) time increases by the device readiness time. Features of the CP-721-1 voltage relay: supply voltage - 100...450V AC maximum load current - 63 A; contacts - 1NO; lower voltage threshold - 140...210 upper voltage threshold - 240...300
