Surge Protector Description: PRD series surge protector for AC 50 / 60HZ, 380 / 440V and below, such as the power supply system on the grid due to lightning or voltage protection. Normal conditions, protection work: 1, Hyperion height does not exceed 2000m; 2, ambient air temperature: the normal range: -5 to + 40 degrees; 3, extended range: -40 to -80 degrees 4, air relative humidity: indoor temperature Under the conditions of 30% -90%; 5, no significant shake and shock vibration place; 6, no explosive medium, the medium does not set to corrode metal and damage the insulation of gas and dust (including conductive dust). Overall and mounting dimensions of the new manufacturers Willow City Schneider mine iPRU-65 / 3P + N, 2-year warranty 1, PRD mining marked 35mm rail mounting; 2, grounding wire should be used more than 4mm square color wire length should not exceed 500mm; 3, in order to prevent the failure of the surge protector affect the normal operation of the power grid, linking to the L line protection should a fuse in series; 4, PRD shape and installation dimensions see manual adjustment, use, maintenance required after installation PRD no need to adjust; as long as protection is installed automatically on the grid properly protected; running to regularly check whether the module signs redness, while observing the fuse indicator is illuminated, the timely replacement of failed components. Failure from the device manufacturers Willow City, the new Schneider mine iPRU-65 / 3P + N, 2-year warranty on the PRD module no failure from the device, when protection from overheating, breakdown failure, failure from the device can be automatically off from the power line, the light signals given at the same time. Signage display protector normal gray, red signs off after failure. Telesignalling shock PRD can be made with a variety of remote signaling contact, if a module protector or more modules fail, the contacts will close, sending fault information.
