Endress+Hauser Single Phase Surge Arrester, Screw Mount Mount

The Endress+Hauser Surge arrester for field mounting is designed to weaken residual currents from upstream lightning protection steps and limit system-induced or system-generated overvoltage surges. The units are primarily used in process-related instrumentation in industries such as chemicals, pharmaceuticals, oil and gas, and in water and wastewater sectors. Key benefits include a compact design for protecting signal and communication cables (optionally available with Ex ia approval) or for simultaneously protecting signal, communication, and power supply cables (optionally available with Ex d approval).
