ABSTRACT:
A circuit breaker has a line terminal comprising a pair of vertically spaced resilient terminal strips which extend in the transverse horizontal direction out from the breaker's housing to free ends of the strips, and which strips have formed therein near those ends respective bends disposed opposite each other and vertically projecting away from each other to bound opposite sides of a circular cylindrical cavity defined between those strips. A horizontal rail for conducting current is aligned in its lengthwise direction normal to those strips, and the rail has a flange received in the cavity in electromechanical contact with the strips, and also, a web extending in the transverse horizontal direction from the front flange out beyond the terminal to a rear flange for the rail. The shape, size and mass of the rail promote reduction of the temperature generated at the line terminal by the inrush of current carried by the rail in the presence of a short circuit in the load served by the breaker.
