SurgeX - SX-N240 - 20A/230V Branch Circuit Surge Eliminator

To offer a proper power foundation, surge protection and conditioning should be installed at the branch circuit level to guarantee full coverage and lessen the need for extra protection downstream.

The SurgeX Branch Circuit lineup provides guaranteed whole room surge protection and conditioning for audio, video, and mission critical equipment at the service panel. Available in three configurations, these solutions are built with NEMA magnetic shielding steel enclosures that meet code for use at the service entrance, sub-panels, and in ceiling plenums.

Engineered with Advanced Series Mode surge elimination and power conditioning technologies, they eliminate all surge energy to properly protect connected equipment from surges, spikes, and electrical transients without producing harmful ground contamination or common-mode disturbances. An all mode impedance tolerant EMI/RFI filter virtually eradicates electrical noise to offer a complete whole room power conditioning solution.


  • NEMA rated magnetic shielding steel enclosure
  • Advanced Series Mode® surge elimination technology
  • Impedance Tolerant EMI/RFI Filter
  • Non-sacrificial components
  • Conforms to UL Std 1283
  • Certified to CSA Std C22.2 No. 8
