Tender specification sheets

Long specification

Multi-pin lightning arrestor according to the requirements of Class I in accordance with IEC 61643-11, EN61643-11:2013. On interface transition from 0 to 1 (acc. to IEC 1312-1), the arrestor serves as lightning protection providing equipotential bonding and is used in applications in accordance with IEC 61643-12. The use of a non-blow-out sparkover gap, in combination with a high-performance varistor, satisfies the inspection requirements for Class I surge protection systems in accordance with the VDEW (Association of German Power Stations) directive. The arrestor is installed in the vicinity of the power supply for the equipment that needs protection, in a standard installation/electrical distribution enclosure. The VPU I 3+1 LCF 280 V/25 kA is used in the TN-C and 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. Rated voltage: 230 VAC lightning test current (10/350 µs): 25 kA protection level with lightning test current < 1.6 kV 25 kA short-circuit strength with max. back-up fuse of 250 A gl Type: Weidmüller VPU I 3+1 LCF 280 V/25 kA Order No. 1351780000 or equivalent

Short specification

Class I arrester for LPL 1 with 25 kA suitable for 230/400 V TN-CS, TT mains systems. Protection level < 1.6 kV. Type: Weidmüller VPU I 3+1 LCF 280 V/25 kA Order no. 1351780000 or equivalent
