Typical Specification
On/Off spring return damper actuators shall be direct coupled type which require
no crank arm and linkage and be capable of direct mounting to a jackshaft up to a
1.05” diameter. The actuators must be designed so that they may be used for either
clockwise or counterclockwise fail-safe operation. Actuators shall be protected
from overload at all angles of rotation. If required, two SPDT auxiliary switch shall
be provided having the capability of one being adjustable. Actuators with auxiliary
switches must be constructed to meet the requirements for Double Insulation so
an electrical ground is not required to meet agency listings. Actuators shall be
cULus Approved and have a 5 year warranty, and be manufactured under ISO 9001
International Quality Control Standards. Actuators shall be as manufactured by Belimo.
Wiring Diagrams
1
Provide overload protection and disconnect as required.

4
For end position indication, interlock control, fan startup, etc., AFB24-S and
AFX24-S incorporates two built-in auxiliary switches: 2 x SPDT, 3A (0.5A)
@250 VAC, UL Approved, one switch is fi xed at +10°, one is adjustable 10°
to 90°.
Meets cULus requirements without the need of an electrical ground con-
