Long specification Single-pole surge protection 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 and is used in applications according 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 meets the inspection requirements for Class II surge protection systems on the basis of the standards. 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 II 1 280 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 In/max (8/20 µs): 20/40 kA protection level < 1.8 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 1 280 V/40 kA Order No. 1352580000 or equivalent
