SineTamer Single Phase DB board Lightning/Transient surge protector 220V/100A/60KA with active tracking AC Sinewave tracking protection- 2 possible ground paths with 3 mode maintenance free protection


The SineTamer© ST-SPT devices provide the best ring wave transient protection available for a device of its type. These devices are intended for single 120, 240, 380 or 480 VAC circuit applications at locations feeding sensitive/critical equipment. It is extremely effective in limiting transients generated inside the facility and is an absolute must on circuits feeding critical microprocessor based equipment. It boasts a robust 60kA per phase peak surge current rating on all models.

This economical device is unique in that it is designed as a stand-alone surge suppression device and requires no special enclosure when used outside an existing enclosure or cabinet. Its compact size makes installation a breeze and the warranty is the best in the industry. Add to all that, dedicated “all mode” Enhanced Sinewave Tracking™ and completely encapsulated Optimal Response Network™, and you get a device that defines effective and reliable surge suppression.

We believe that we offer the most versatile TVSS devices on the market with performance specs that are superior to our competitors and a warranty that is second to none.
