Phase control relay CZF-BR (3x400/230+N 8A 1changeover IP20 DIN-rail mount) F&F EA04.001.003 Euroautomatika F&F

"CZF" series phase control relay DIN-rail mounting. Designed for the protection of electric motors and electrical installations powered from a three-phase network in cases of: absence of at least one phase, voltage asymmetry, or neutral wire breakage. Operating principle If the voltage is within normal limits, the contacts of the output relay are closed and voltage is supplied to the motor control contactor, controlling its activation. In the event of any of the above-mentioned fault conditions, the relay contacts open and the contactor is disconnected. Activation occurs automatically after the restoration of the mains supply voltage. Features: phase presence monitoring; asymmetry monitoring between phases; protection against neutral wire breakage; supply voltage 3x230+N V AC; contact - 1NO, 1NC (2x8 A).
