Corrpro® secondary lightning arresters are designed to prevent electrical surges from lightning, load switching or other sources from exceeding the insulation barrier of your equipment. They divert the electrical surge away from your equipment by providing an alternate low resistance path to ground during periods of abnormally high voltage.
Our DC lightning arresters are certified to CSA C22.2 No. 269.4-17 Type 4 and UL 1449 standards, and come in a variety of configurations to meet your needs. They are available with and without a ground wire, and the mounting terminals fit standard rectifier output lug spacing.
