| Long specification | Single-pole surge voltage arrestor according to the requirements of Class II/III acc. to IEC 61643-11, EN61643-11:2013. Consisting of V0 material, the arrestor serves as surge protection in applications acc. to IEC 61643-12. Surge protection is used in the TN, TT and IT mains system types in combination with several lightning protectors. 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 1 R LCF 280 V/40 kA is earthed, in combination with three or four identical arrestors, between the outer conductors (L1, L2, L3 and / or the neutral conductor). Reference is also made here to the 3+1 circuit and the 3+0 / 4+0 circuits. 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 maximum discharge current (8/20 µs): 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 1 R LCF 280 V/40 kA Order No. 1352750000 or equivalent |
