Eaton's Cooper Power™ series Kearney disconnect and oil circuit recloser bypass switches feature all copper bar current-carrying parts, providing uniform strength and conductivity with no hidden defects. Eaton's 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.
