Features

These transient voltage surge suppressors (TVSS) are engineered for reliability, flexibility and long life in the most extreme surge environment. The true maximum surge current rating, unlimited by fusing, has been proven successful in 3rd party tests.

These devices are available in a standard NEMA 12 enclosure. Optional enclosure types include NEMA 12 and 4X, flushmount, surface mount and stainless steel. These units have been tested to surge current ratings per NEMA LS-1, up to 200kA per mode, including the fuses in the surge path. Standard features include a surge counter, audible alarm, indicating lights, dry contacts, and an integral surge rated disconnect**. Rating options range from 65kA per mode to 300kA per mode.

All mode protection is provided with surge components (MOVs) connected on the phase to neutral, phase to ground, and neutral to ground paths as appropriate for the voltage configuration.
