Flameproof surge arrester for the data and power side for protecting one 120 / 230 V power supply system and one 24 V data interface of field devices in potentially explosive areas (zones 1 and 2).Additional safety due to fault-proof Y circuit for 120 / 230 V power supply systems.
■ Dual surge protection for one 120 / 230 V power supply system and one data interface
■ Easy to mount on field devices with a spare cable gland
■ For installation in conformity with the lightning protection zone concept at the boundaries from 0B – 2 and higher
