Voltage Relay CP-731 (three-phase; microprocessor; upper and lower voltage limit monitoring; asymmetry monitoring; phase sequence; DIN rail mounting 35mm 3x400/230+N 2x8A 1Z 1R IP20) F&F EA04.009.005 Evroavtomatika F&F

"CP" series voltage relay DIN-rail mounting. Designed for continuous monitoring of voltage magnitude in a three-phase AC network and protection of electrical installations, electrical appliances, and other electronic equipment from overvoltage or undervoltage, and from neutral wire breakage. Protection is provided by disconnecting the load from the power supply. The upper and lower voltage limits are set by the user using potentiometers on the control panel. The relay measures the network voltage and, if the voltage goes beyond the set limits or if there is a neutral wire breakage, the relay disconnects the protected equipment. After the network voltage is restored, the relay turns on automatically. Features of the CP-731 voltage relay: three-phase; voltage asymmetry control; phase merger control; phase sequence control; supply voltage - 3x(150...450)+N V AC; maximum load current - 2x8 A; contacts - 1NO, 1NC; lower voltage threshold - 150...210 upper voltage threshold - 230...190
