The LineDefender™ design enables utility personnel to do their jobs simply and safely. It combines outage prevention reclosing technology with the safety and intuitive ease-of-use lineworkers deserve. Upon reclosing lockout, the device remains in the cutout. Resetting the LineDefender is as easy as actuating the yellow handle safely from the ground. Eliminate arcing exposure by using the vacuum bottle to pick up load. Tripped reclosers are easy to find with a flashing beacon and a wide-angle semaphore. The maintenance-free design can easily replace a fused cutout, allowing cost-effective deployment toward the circuit edge. The LineDefender works with GridHUBB™, a complementary software platform for Hubbell intelligent devices, which enables utilities to create, manage, and commission settings in an intuitive application packed with powerful tools and advanced reporting.
