摘要： A terminal connecting device has a plurality of movable contacts which are biased toward each other by springs to an extent limited by a spacer carried by the frame. The device is easily assembly by fitting shafts through bores in the contacts and using spring holders inserted between pairs of contacts and locked by wedges to exert a biasing force urging opposed contacts together. The shafts are held by support and frame members having open recesses, as opposed to bores, therein.

摘要： An arc-suppressing apparatus for a circuit breaker has a pair of side plates having a plurality of first and second grooves formed therein, the second grooves being shallower than the first grooves and extending linearly from the ends of the first grooves to an end of each of the side plates. The side plates are separated by a spacing strut and loosely connected by a bolt and nut so that a space exists between the plates which is large enough to allow a plurality of grids to slide along the second grooves into the first grooves. Thereafter, the nut and bolt are tightened to firmly secure the grids in the first grooves.

摘要： A drawer-type circuit breaker of the type adapted to be disposed in an engaged and disengaged position within a housing and a disengaged position outside the housing on extendable support rails is provided with latches which will prevent the extension of the guide rails until the circuit breaker is moved from the engaged position to the disengaged position within the housing. The movement of the circuit breaker to the disengaged position operates the latches to permit extension of the support rails while still preventing movement of the circuit breaker onto the support rails. Movement of the support rails to the fully extended position allows the latches to be released by movement of the circuit breaker to allow the circuit breaker to be withdrawn out of the housing onto the support rails. Actuating levers for engaging and disengaging the circuit breaker are provided on opposite sides of the circuit breaker for movement in respective slots and notches to smoothly and efficiently carry out the engaging and disengaging operation while preventing undesirable vertical movement of the circuit breaker relative to the housing.
