TNF24 Typical Specification
On-off spring return damper actuators shall be direct
coupled type which require no crankarm 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, one SPDT auxiliary switch
shall be provided having the capability of 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 are
UL listed and CSA certified and be manufactured under ISO
9001 International Quality Control Standards. Actuators
shall be as manufactured by Belimo.
