Multi-pole surge voltage arrestor according to the requirements of Class II acc. to IEC 61643-11, EN61643-11:2013. Consisting of V0 material, the arrestor serves as overvoltage protection and is used in applications according to IEC 61643-12. The use of a high-performance varistor in combination with sparkover gaps satisfies the inspection requirements for Class II surge protection systems on the basis of the standards. The leakage current-free arrestor is installed in the vicinity of the power supply for the equipment that needs protection, in a commercially available installation/electrical distribution enclosure. The VPU II 4 R LCF 280 V/40 kA is used in the TN-S mains network. With thermal separation device on the varistor. If protection is no longer available, the colour in the display window changes from green to red. The functional state is also displayed by a voltage-free signalling contact (changeover). Rated voltage: 230 VAC In/max (8/20 µs): 20/40 kA protection level < 1.8 kV combined pulse Uoc: 10 kV 25 kA short-circuit strength with max. back-up fuse of 125 A gl telecommunication output: contact: 250 V/0.5 A 48 VDC/0.1 A Type: Weidmüller VPU II 4 R LCF 280 V/40 kA Order No. 1352780000 or equivalent
