Abstract
A blade suspension assembly for a circuit breaker comprises a pivot pin, a torsion spring, an elongated blade, and a blade carrier. The torsion spring includes a lateral middle section, a pair of end legs disposed on opposite sides of the middle section, and a lateral hole extending therethrough. The blade includes an electrical contact mounted thereto, a lower bearing surface, and a lateral circular aperture. The blade carrier includes first and second pairs of bearing surfaces. To assemble the blade suspension assembly, the torsion spring is placed over the blade with the lateral middle section abutting the lower bearing surface of the blade, with the end legs disposed on opposite sides of the blade, and with the lateral hole in the torsion spring disposed in line with the circular aperture in the blade. Next, the pivot pin is inserted through the lateral hole in the torsion spring and through the circular aperture in the blade. The combination of the blade, the torsion spring, and the pivot pin is then inserted into the blade carrier with the pair of end legs abutting respective ones of the first pair of bearing surfaces and opposite ends of the pivot pin abutting respective ones of the second pair of bearing surfaces.
