The invention discloses an energy-saving integrated type single-phase 
alternating current motor starting protector and belongs to the technical field of 
refrigeration compressors. The energy-saving integrated type single-phase 
alternating current motor starting protector comprises a shell, a single-phase 
alternating current motor 
starter, a single-phase alternating current motor protector and a shell cover. A 
positive temperature coefficient 
thermistor cavity and a single-phase alternating current motor protector cavity are formed inside a shell cavity in an enclosed mode. The single-phase alternating current motor 
starter comprises a 
positive temperature coefficient 
thermistor, a first pin and a second pin. The single-phase alternating current motor protector is arranged inside the single-phase alternating current motor protector cavity. The shell cover is matched with the shell and is provided with a grounding pin, a pin N and a pin L. The energy-saving integrated type single-phase alternating current motor starting protector is characterized in that the single-phase alternating current motor protector comprises a base, a fixing seta, double 
metal sheets, 
electric heating wires, a first protector pin, a second protector pin, a movable contact reed and an ejection rod. The energy-saving integrated type single-phase alternating current motor starting protector has the advantages of being reliable in positioning, capable of improving installation efficiency and guaranteeing overall heating effects of the double 
metal sheets, convenient to manufacture and assemble, remarkable in energy-saving effect, and capable of simplifying a mould structure used for manufacturing the shell, preventing electrical short circuits, preventing the shell from deforming and being damaged due to heating and guaranteeing the stability and reliability standards of the pins.
