Central air conditioner compressors Submersible pump motors Motors generally over 1/3 HP with start capacitors General Description Operation A voltage sensitive, electromagnetic type motor starting relay with normally closed snap-action contacts used to disconnect the start capacitor on capacitor-start, induction-run and capacitor-start, capacitor-run motors. The relay has a protective cover which eliminates the need for additional electrical and mechanical protection. A variety of mounting brackets are available. Terminals may be either Quick Connect Tab Type or Screw Type. The relay is energized by a magnet coil electrically connected across the start winding of the motor and responds to the increase in start winding voltage as the motor accelerates from zero to the normal running speed. The relay contacts are actuated by the armature of the relay to disconnect the start capacitor at a speed where the motor has sufficient torque to bring it up to normal running speed. The relay remains energized during the run operation of the motor, keeping the relay contacts open. When the motor is de-energized, the relay contacts re-close for the next motor start. Each relay is designed for a specific application which includes the coil rating for continuous run voltage and the pickup and dropout calibration for proper motor starting. Terminals Quick Connect Type 0.250” x 0.032” (6.3 mm x 0.8 mm) Electrical Ratings Screw Type, Tin Plated Brass #8-32 Thread Contacts 35 Amperes max, 50/60 Hz, break only See Appendix “B” of General Information Brochure for Coil Groups and Ratings. Continuous Coil Rating 60 Hz; 130 to 500 Volts 50 Hz; 117 to 470 Volts Endurance 100,000 to 500,000 operations (depending on load) Mounting Mounting Bracket Select from available brackets in Appendix “C” of the General Information Brochure Appendix “C” of the General Information Brochure. . Mounting Position Each relay is calibrated in the intended mounting position. Specify desired mounting position from Circuits If there is a terminal in position #6, it must be the same polarity as terminals #1, #2, and #4 to prevent possible flashover. If there is no terminal in #6 position, #4 can be either polarity.
