Efforts to protect electrical circuits from fault currents led to a new device, the current limiting protector (CLP), which combines a copper-bar solid conductor in parallel with a conventional silver and current-limited fuse within a 28 x 7-inch fiberglass cylinder. A fault current causes chemical reactions in the copper bar and diverts current into the conventional fuse, which melts and safely interrupts the fault current. Successful short-circuit tests of the CLP indicate substantial first-cost and operating-cost savings. 1 figure. (DCK)
