M7415A, M8405A Damper Actuators

Provides control of economizer systems on HVAC equipment.

Actuator Rotation:

Closed position is the limit of clockwise rotation; open position

is the limit of counterclockwise rotation as viewed from the

shaft end of the motor.

Auxiliary Switch Rating (M8405A only):

24 Vac, 20 VA inrush, 20 VA run.

Terminal Connections:

1/4 in. (6 mm) male quick connect terminals mounted on actua-

tor. Terminal arrangement is dependent on actuator model.

Ambient Operating Temperature Range:

-40°F to +125°F (-40°C to +52°C).

Voltage and Timing:

See Table 1.

Dimensions:

See Fig. 4.

Shaft:

Single-ended drive shaft with crank arm supplied.

Flammability Rating:

Underwriters Laboratories Inc. UL94-5V.

Approval:

Underwriters Laboratories Inc. Component Recognized: File

No. E4436, Guide No. XAPX2, Vol. 9, Section 1, 7-25-83.
