A protective device ( 1 ) which is attached on an internal side of a compressor, includes a housing ( 10 ) of an insulating material, a motor protector ( 20 ) placed on the housing ( 10 ) and having a thermally responsive switch inside, a fuse device ( 30 ), a connective terminal ( 40 ) electrically connected to a hermetic terminal in the compressor, and a quick connect terminal ( 50 ). A portion ( 11 ) of the housing for varying an installation position of the connective terminal ( 40 ) includes a plurality of vertical grooves ( 11 a) and a horizontal slot ( 11 b). These grooves and slots ( 11 a and 11 b) are formed equally spaced from one another at a periphery of the housing ( 10 ). The connective terminal ( 40 ) has an engaging part ( 41 ) and a fuse connecting part ( 43 ). The fuse connecting part ( 43 ) is inserted through the horizontal slot ( 11 b), and the engaging part ( 41 ) is engaged with a selected vertical groove ( 11 a) to determine a direction and/or a position of the protective device ( 1 ) in the compressor. The installation position of the connective terminal ( 40 ) for the housing ( 10 ) can be varied by selecting any groove ( 11 a) of the plurality and the protecting device ( 1 ) can be arranged in a small space depending on the specifications of the compressor.
