115 VAC motor is an enclosed, permanent split capacitor induction type. The motor is equipped with a thermal overload device that opens and resets automatically. Standard motor requires 28-33 mfd capacitor supplies by either the customer, or Duff-Norton at extra cost, for loads up to 250 pounds. High speed motors require a 64-72 mfd capacitor, also available from Duff-Norton. A capacitor box is available on AC models only.

220 VAC motor is totally enclosed, permanent split capacitor induction type. Load/no-load speeds are approximately equal. Equipped with thermal overload device that opens and resets automatically. Standard motor requires 10 mfd 440VAC, 60/50Hz metalized polypropylene capacitor supplied by Duff-Norton.

Controls are also available for these actuator models as follows:

Control Package PAC -1CR = PSPA 3410
Control Package PAC-2CR = PSPA 4410

Additional Notes

Some actuator surface temperatures may reach 230°F at or near maximum allowable duty cycle.
The thermal overload resets in 10 minutes.
All ratings are normal and based on the actuator being broken in for approximately 2500 inches of travel.
2 DPST-NO relays (supplied by customer) are required to operate the actuator if the Duff-Norton Controls are not used.
