Abstract

227,928. Reyrolle & Co., Ltd., A., and Coates, F. Oct. 26, 1923. Fusible cut-outs.-In electric fuses for high tension circuits, the current under short circuit conditions is limited by embodying sufficient resistance in the fusible element itself, the fuse wire or strip being covered with a refractory insulating material such as asbestos and wound in spiral or like form so as to give the required resistance with a comparatively short distance between the terminals. In the form shown, the wire A, covered with asbestos A', is wound spirally on an insulating support B and is enclosed in a casing D which may be filled with marble dust or with an insulating compound. The covered wire spiral may be attached to the support by a coating of vitreous or like adhesive insulating material. In other forms, the support B may be provided with a spiral groove to receive the wire or the wire spiral may be completely embedded' in insulating material forming the support. According to the Provisional Specification, bare wire may be employed.
