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 no-blow-out spark gap, in combination with a high-power varistor, fulfils the inspection requirements for Class I surge protection systems according to the VDEW (Association of German Power Stations) directive. The arrester is installed in a commercially available installation/electrical distribution enclosure, in the vicinity of the power-supply unit for the equipment that needs protection. The VPU I 3+1 R 400 V/25 kA is used in the TN-C and TN-C mains network. With thermal separation device on the varistor. In case of insufficient protection, 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: 400 V AC lightning test current (10/350 µs): 25 kA protection level with lightning test current < 1.9 kV 25 kA short-circuit withstand rating with max. back-up fuse of 250 A gl telecommunication output: contact: 250 V/0.5 A 48 VDC/0.1 A, type: Weidmüller VPU I 3+1 R 400 V/25 kA, Order No. 1351880000 or equivalent

Short specification

Class I arrester for LPL 1 with 25 kA, suitable for 400/690 V TN-CS, TT mains systems. Protection level < 1.9 kV. With remote alert, type: Weidmüller VPU I 3+1 R 400 V/25 kA, order no. 1351880000 or equivalent
