Leakage relay is designed to protect people from electric shock and prevention of hazardous consequences of current leakage to ground in three-phase AC voltage of 127 or 220 V with isolated neutral of the transformer by reducing the overall insulation resistance to a dangerous extent. Relay leak has condition control basics-tion of circuit elements, and automatic adaptation to voltage over-shishimai network 127 or 220 V Relay can be used in mines, including dangerous on gas or dust in ambient air from minus 10 to plus 35 °C and relative humidity of 98% at a temperature of 35 °C. TECHNICAL CHARACTERISTICS rated voltage of the protected network frequency of 50 Hz, 127, 220 Level and the type of protection Ia RV 2B Degree of protection IP54 Resistance to actuation in a symmetric three-phase leakage, ohms per phase, not less than: (a) when the voltage is 127 V, 3.3 b) at a voltage of 220 V, 10 a tripping Resistance for single phase leakage and the rated voltage, ohms, not more than: (a) when the line voltage is 127 V, 10 b) at a voltage of 220 V, 12 Own time, the relay leakage during the occurrence of single-phase leakage resistance of 1 kOhm, not more than 0.1 overall dimensions, mm 260×320x320 Weight, kg, not more than 20 12.0159412.025 TU-89
