TLF24 (-S) 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 shaft up to a 3/4” diameter
and center a 1/2” shaft. 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
switch 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.
