PR-O-TECT
For enhanced surge/spike suppression, PR-O-TECT surge protection modules can be factory installed and wired onto a Three Phase Reactor. In this installation the reactor and surge protection module work together for maximum attenuation of spikes. The reactor helps to extend the module life by attenuating the most severe parts of the spike.

Installation of surge protection modules is simple- the green wire is connected to your system ground terminal. The other wires connect to each of your three phase conductors.

PR-O-TECT Three Phase Surge Protection Modules offer protection of diodes, transistors, thyristors, SCR’s, etc. from dangerous voltage transients. They can reduce overall system operating costs by reducing equipment down time and maintenance costs, while improving system efficiency and reliability. Surge protectors will reduce the effect of lightning and even reduce radio frequency interference. Use PR-O-TECT Surge Protection Devices to protect adjustable speed drives, process control equipment, servo drives, uninterruptible power supplies and other sensitive electronic equipment.
