AC electromechanical relay MFU 260

1 NO/NCsingle-phaseDIN rail

Window voltage relay UC 50...270 V 50/60Hz, 1 changeover contact, adjustable UC 65...260 V Contact - Change-over (voltage-free) Voltage - UC 50 … 270 V 50/60 Hz Measurements - 87 x 17,5 x 60 mm The MFU monitoring relays operate in window mode, i.e. they check whether the monitored voltage is between a lower and an upper threshold. The threshold values of the overvoltage and undervoltage are set via two potentiometers. If the monitored voltage exceeds or falls below the set upper threshold or the set lower threshold for a longer time than the reaction time set on the front, the output relay opens. Measuring voltage is equal to supply voltage. Approvals: UL and CSA. 1 change-over contact, setting range UC 65...260 V, The window relay detects over- and undervoltage, independent setting options of undervoltage and overvoltage, 2 LEDs for operating voltage and relay output, adjustable response time, measuring voltage is equal to supply voltage, hysteresis fixed = 3% of setpoint, measurement of true RMS value, degree of protection: housing IP 30, terminals IP 20, approvals: UL and CSA, housing 17.5mm
