Electrical connection 3 FT, 18 GA plenum rated (UL CL2P), 1/2 in. conduit connector. Overload protection electronic throughout 0 to 95?é?? rotation. Belimo NM24 US Damper Actuator, On-Off, Reversible, Non-Spring Return, Direct Coupled, Floating Point, 24V
Application - For modulating or on-off control of dampers in HVAC systems. Actual actuator sizing should be done in accordance with the damper manufacturer?ó?é¼?äós specifications. Control is on-off from an auxiliary contact of a fan motor contactor, or a manual switch. The direction of rotation is reversible, for use with a floating point type control. The actuator mounts directly to the damper operating shaft with a universal V-bolt clamp assembly. Operation - The universal mounting bracket supplied with the actuator will prevent lateral movement of the actuator. The damper actuator is not provided with and does not require any limit switches, but is protected against overloading. The angle of rotation is mechanically limited to 95?é??. When reaching the damper or actuator end position, the motor stops automatically. The gears can be manually disengaged by simply pressing down the spring loaded button on the actuator cover. When this button is pressed down, the damper blades can be adjusted by hand. The position of the actuator is indicated by a visual pointer. Auxiliary switches are easily fastened directly onto the actuator body for signalling and switching functions.. Belimo. Belimo. NM24 US.
