Product parameters Function: IPR replaceable part can quickly be replaced, it is not only a window with a visual indication, but also long-distance transmission "may replace part needs to be replaced" information. The maximum continuous operating voltage UC depends on: grounding system. Protection: Common mode / differential mode. Purpose: lightning protection electricity influx line protection: IPR100r / IPR65r for extremely hazardous situation (in harsh environments), IPR40r / IPR40 for highly hazardous situations, IPR15 for low hazard situations. Grade II: IPR8 for load secondary protection, and into the line side of the surge protector by a cascade arrangement, voltage-limited, 8 / 20μs waveform. 2, the maximum discharge current: 100/80/65/40/15 / 8kA. 3, the nominal discharge current: 60/50/40/30/20/15/5 / 2kA. 4, the voltage protection level: 1.8 / 1.8 / 1.8 / 1.8 / 1.2kV. 5, the working environment temperature: -25 degrees - +60 degrees. Schneider IPR surge protector is used for AC 50Hz, rated voltage up to 380V IT, TT, TN-C, TN-S, TN-CS and other power supply system, and a direct lightning indirect effects of lightning or other transient over voltage of Surge protection Schneider surge protector works IPR IPR is a port, electric shock protection, indoor-mounted installation, the internal voltage-limited IPR as from the device, when the IPR due to overheating, breakdown failure, from the device can automatically will play from the power line out, but gives an indication of the signal, when working properly, the visual window display white, after the failure from the display between the red in the three-phase four-wire system, three phase lines and one zero line docking ground Each protector, the protector under normal circumstances in a high resistance state, the grid because of lightning or other reasons when a surge overvoltage protection immediately turned quickly in the nanosecond time, will surge into the earth, to protect the power line of electrical equipment. Schneider IPR surge protector installation: usually installed in the inlet low voltage distribution cabinet, not more than 500mm to prevent the failure of the surge protector affect grid work, linked to the L line protection should the series with a fuse or circuit breaker . Compliance: 18805.1 / IEC61643-1 network rated voltage: Un: 220/380 VAC maximum continuous operating voltage Uc: 275/420 140/275 maximum discharge current Imax (8 / 20uS): 65/40/15 / 8kA nominal discharge Current In (8 / 20uS): 20/15/5 / 2kA poles: 1P + N / 2P / 3P + N / 4P 2.5-25 mm2 cord white working status display window by a mechanical indicator: normal operation Red: already defective and need replacing response time: less than 25ms
