Product DescriptionSurge arrester HYS4-C is used as potential connection during the lightning strike, etc, for the power supply system of AC 50HZ/60HZ, 380V and that of below, such as TT, IT, TN-S, TN-C-C, etc. It’s designed according to IEC-61643-1, GB50057-97. The sheathing is mounted on electric track of 35mm, and a failure release system is built in the product, when breakdown of power supply protector fails due to over-current and over-heat, the failure release system can release itself automatically from the electricity network, and the visual alarm indication module can be replaced when there is operating voltage. CharacteristicsTo replace the protector unit is available without power off. It can accept the lighting current impulsion up to 40KA (8/20μs), the motor reaction time is fewer than 25 nanoseconds and the color of visual window shows the operating condition of the protection with green (Normal) and red (Failure) Mounted Position and ApplicationSPD protection for Grade C lightning protection current is used as potential connection during the lightning strike, etc. It’s mounted at LPZOB or at the juncture site of section LPZ1 and section LPZ2, and usually mounted at floor electric switch bow and the electric distribution box in the following places: computer center, telecommunication machine room, elevator monitoring room, control room of frequency conversion equipment, operating room and care unit of hospital and the places with electronic medical equipment, as well as mounted in the lightning principal power distribution box of the building with the storey less than 6. And for dispersed, SPD should be mounted in the power distribution box of the user’s.
