3ARR22 Type
General Description
A higher rated, 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 apacitor-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. Typical Applications
• Central air conditioner compressors with higher rating requirements
• Submersible pump motors with higher rating requirements
• Motors generally over 1/3 HP with start capacitors
Operation
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, Tin Plated Brass 0.250” x 0.032” (6.3 mm x 0.8 mm)
• Screw Type, Tin Plated Brass #8-32 Thread
*Spare terminals for interconnections are available.
