GY08 series No power passive motor protector (hereinafter referred to as the "protector") applied to ac 50 Hz,make up the electric control circuit of protection with switching device, such as AC contactor under voltage 24V to 380V power supply circuit . When abnormal operating state of the main circuit , such as open phase, overload,unbalanced three-phase, protector can cut down switch electric contact, disconnect the three-phase power supply of the motor in time, fast, reliable. Use current sampling inspection technology of cores without auxiliary power supply, possess energy saving electricity function, silicon controlled rectifier output, novel design, simple structure, easy to use, reliable operation, no power consumption, long life and no arc generation, etc. Comply with the requirements of en60947-a, en60947-5-1, AN60204-1 and GB14048.4.

Technical parameter
Low voltage protection：When the three-phase power supply of the motor is missing or the internal phase of the motor is broken, the protector reacts in 1 second and the LED phase lights go out.
Unbalance protection of three-phase current：The difference between any two phase current is greater than 50%, the protector reacts in 1second.
Overload protection：When the working current of the motor is more than 1.2 times of the set value, the protector reacts in 80-10 seconds (anti-timing characteristic) and the LED light is lit.
Motor Shaft Lock Protection：When running current exceeds set multiple 5 times, the protector reacts in 2 seconds.
Output interface reset mode: control loop power failure reset (60 + 10%) seconds.
Output interface load capacity:AC380V/1A、COS ∅=0.3-04
The continuous working system is applicable to the three-phase motor: AC24V - 380V / 50Hz, minimum sampling current ≥3A (the number of turns of the turn of the circle is enlarged when < 3A).
