Protective device for a hermetically sealed type compressor and a hermetically sealed compressor listing same

摘要

A protective device (3) for a hermetic type electromotively driven compressor (1a) includes a protector assembly (30) having a housing (32) with an electric current fuse (34) which detects a predetermined over-current. The housing (32) comprises an electrically insulating skirt member (31) formed so as to block a conductive part on the side facing an external connection terminal. By forming the electrically insulating skirt member (31) of housing (32) for a hermetic type electromotively driven compressor, insulation distance between a conductive part such as the electric current fuse (34) and an external conductive part such as a metal wall part (21) is set to be 9.5 mm or more.
