Imitation Schneider surge lightning surge breaker earth leakage circuit breaker 4P20KA

Surge protectors Description: PRD series surge protector for AC 50 / 60HZ, 380 / 440V and below the other power supply system on the grid due to lightning or voltage protection. Protection of normal conditions: 1, Hyperion height does not exceed 2000m; 2, ambient air temperature: normal range: -5 to + 40 degrees; 3, extended range: -40 to -80 degrees 4, relative humidity: Indoor temperatures at 30% to 90%; 5, no significant shake and shock vibration place; 6, the absence of explosive medium, the medium does not set to corrode metal and damage the insulation of gas and dust (including conductive dust). Outline and installation size 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, after a surge protector in order to prevent the failure affect the normal operation of the power grid, linked to L Line protection should be in series with a fuse; 4, PRD shape and installation dimensions see instructions adjustment, use, maintenance PRD press requires installation does not require adjustment; as long as the protection is installed automatically on the grid properly protected; you want to run regularly check whether the module signs redness, while observing the fuse indicator is illuminated, the timely replacement of failed components. The failure from the device PRD module no failure from the device, when protection from overheating, breakdown failure, failure from the device can automatically remove it from the power line, the indicator gives signals simultaneously. Protection normal signs grayed, after failure from the label red. Telesignalling shock PRD can be made with a variety of remote signaling contact, if a module protector or more modules fail, the contact will close, sending fault information.
