Bimetal operated current sensitive relay for disconnection of auxiliary
windings and start capacitors of single phase AC motors. The operating
time of the auxiliary winding is a function of the starting current and its
duration. High contact pressure reduces sensitivity to shock and
vibration - no contact sticking.
Other features: independent of mounting position and location. Under
stalled motor conditions the auxiliary winding and/or the starting
capacitor will remain disconnected avoiding damage to the motor.
See page 281 for additional information.
