OVRHT3D
OVRHT3D is ideal for use in sub-distribution and point-of-use applications like UL 508 panelboards helping protect sensitive electronic equipment against the damaging effects of power surges caused by lightning, utility load switching, internal load switching, and more. Its space-saving design is ideal for compact installations. With individual thermally protected MOVs, the OVRHT3D takes itself offline safely without the need for overcurrent protection.
