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 R 48V is earthed between the phase and the neutral conductor. With thermal separation device on the varistor. If there is no longer any protection, the colour of the LEDs changes from green to red. The functional state is also displayed by a voltage-free signalling contact (NC contact). Rated voltage: 48 VAC/DC In/max (8/20 µs): 2 kA protection level < 0.95 kV load current Il: 16 A telecommunication output: contact NC: 250 V/0.5 A 48 VDC/0.1 A Type: Weidmüller VPU III R 48V Order No. 1351600000 or equivalent
