Surgelogic™ SurgeLoc is the industry.s first field installable internally mounted SPD in NQ panelboards. With a wide range of protection modes, enchanced EFI/RFI filtering, and a unique design these field retrofits can be fully installed in NQ panelboard in approximately 2 minutes. They provide better performance with a diagnostic interface with audible alarm, dry contacts surge counter, and phase testing. Space saving features allows you to use standard size panels, requiring only up 6 inches of increased panel size based on the number of breaker slots needed. These surge protection devices all have a short circuit current rating of 200 kA, 10 year product warranty, and 6 modes of protection. This particular model is 3 phase, 4-wire + ground, 20 kA nominal current, 208Y/120 V, and with a surge current rating 200 kA. The device is engineered to UL 1449 4th Edition, type 1 SPD, and complies with UL 96A for Lightning Protection Systems. : Provides suppression to vulnerable equipment powered from weather exposed panels.; High performance surge suppression even in severe electrical conditions.; Provides premium surge suppression while managing both thermal and high-current end-of-life events.; Immediate notification through audible, visual and remote signaling if reduced suppression occurs.; Improves surge suppression and reduces high frequency noise.; Provides immediate response if suppressor is damaged.; Flexibility to install on line side of service entrance applications.
