1.Construction and Feature

 

In a device, the contactor is converted between normally open or normally closed by positive/anti pulse voltage exciting the coil instead of long-term power supply and the contactor of relay keeps closed just withthe magnetic power of permanent magnetic steel. Over the electromagnetic replay, permanent magneticrelay takes the advantage of less consumption in energy and material, stable performance, smaller size, larger carrying capability, and electromagnetic driving mechanism consumption current is approximately 30mA, while the one of permanent magnetic mechanism is approximately 5mA.Automatic reset function: As the break of neutral line and the potential offset lead to overload or under voltage of single-phase line, the protector automatically trip and cut-off the power supply and automatically switch to the load source after e-minute-delay later after the electric network is recovered to normal value so as to protect electrical equipment from over/under voltage. The case is in fire-retardent material, concise and lively outline, modular design, reail mounting.Bi-color LED display work state: green(normal), red(faulty)

2.Application

The potential offset protector is a terminal protecting device of power distribution system of voltage of 500V and below. In low-voltage distribution line with rated voltage 220V, rated current 10~63A, working frequency of 50Hz, it protects the household appliance as the neutral line potential offset causes over/under voltage..
