Tender specification sheets

Long specification
Surge protection according to the requirements of Class III in accordance with IEC 61643-11, EN61643-11:2013. The arrestor serves as surge protection and is used in applications in accordance with IEC 61643-12. The arrestor is installed in the vicinity of the equipment that needs protection in a standard installation/distributor housing. The VPU III SO LD +A is earthed between the phase and the neutral conductor. With thermal separation device on the varistor. If there is no longer any protection, the red LED goes out and an acoustic signal sounds. Rated voltage: 230 VAC In/max (8/20 µs): 1.5 kA protection level < 1.5 kV Type: Weidmüller VPU III R SO LD A Order No. 1351700000 or equivalent 
Short specification
Class III arrester with Uoc: 3 kV suitable for 230 V AC mains systems. Protection level < 1.5 kV. With red LED display and acoustic alert Type: Weidmüller VPU III SO LD A Order no. 1351700000 or equivalent
