Abstract
A motor protector has a tubular metal housing with open and closed ends, has a contact welded to one inner side of the housing near the closed housing end spaced from an opposite inner side of the housing, has a terminal sealed in the open housing end, and has a bimetal member extending from the terminal into the housing along the housing axis in spaced insulated relation to the housing to move into and out of engagement with the contact in response to temperature change. The protector is compact and hermetically sealed and is calibratable by housing deformation without loss of hermetic sealing. In some embodiments first and/or second heaters connected to selected motor windings via sealed terminals are compactly accommodated in the housing along respective sides of the bimetal member.
