Cooper Power Systems Kearney ™ disconnect and oil circuit recloser bypass switches feature all copper bar current-carrying parts, providing uniform strength and conductivity with no hidden defects. Silver washers between the blade assembly and hinge act as a bearing, ensuring easy blade opening, even after long exposure to contaminated atmospheres. The H-72 switch has silver inlays blazed to the hinge and jaw stationary contacts. The truss-type blade assembly with wide hinge and formed channel blades assures proper blade alignment during closing, even with applied side forces. The positive blade latch prevents nuisance openings and opening under fault conditions. The positive pryout affords easy opening under icing conditions. The D-73, M-72 and H-72 models feature a 90° field removable stop. The stop pin can be removed if 180° blade travel is required. Tinned terminal pads accommodate either bronze or aluminum terminals.

Cooper Power Systems Kearney regular and current transformer bypass switches feature sequenced, make before break operation in both 600 A and 1200 A ratings, minimizing the possibility of operator error. The single pull operation of the 600 A ratings both bypasses and disconnects the regular or current transformer, or reconnects them to the line. The two-pull operation of 1200 A ratings minimizes the operating effort of these heavy-duty switches. An Arcrupter or snaphorn provided on regulator bypass switches interrupts the regulator exciting current and prevents arcing and damage to the switch contacts when disconnecting the regulator. Reverse loop contacts on 600 A ratings increases contact pressure and minimizes the possibility of contact damage when subjected to high fault current.
