Resideo Braukmann ml6161a2009/u Damper Actuator Floating Point Non-spring Return 35 In-lb 24V Ac Nema 1

Product Description

The Resideo Braukmann ML6161A2009/U is a floating point, non-spring return damper actuator designed for use with dampers and valves in commercial and residential HVAC systems. This direct-mount actuator delivers 35 in-lb of rated torque and operates on 24V AC power, making it a reliable choice for HVAC technicians working on air handling units, VAV systems, and ductwork damper control applications. Because this is a non-spring return actuator, it does not include a fail-safe mechanism to move the damper during a power outage. This design makes the unit more compact and easier to service compared to spring-return alternatives. It is well suited for non-critical HVAC zones where fail-safe positioning is not required. The ML6161A2009/U supports shaft rotation in both clockwise and counterclockwise directions and accommodates stroke degrees of 45, 60, and 90 degrees. It fits round and square shafts ranging from 3/8 inches to 1/2 inches in diameter, offering broad compatibility across damper assemblies from multiple manufacturers. The actuator features two auxiliary switches with an SPDT contact form, which can be used to trigger additional control signals or interlocked equipment in the HVAC system. It carries a plenum rating, meaning it is approved for installation inside air plenums where low-smoke and low-toxicity requirements apply. With a NEMA 1 enclosure rating, this unit is suitable for standard indoor installations. Power consumption is 1.8 VA with a power rating of 2.25W, keeping energy draw low during continuous operation. The unit is certified to CE, CSA, and cUL standards and listed under UL File No. E4436, Guide No. XAPX2. Operating temperature range spans from 20 degrees Fahrenheit to 125 degrees Fahrenheit, covering typical mechanical room and plenum environments. HVAC controls technicians and building automation professionals will find this actuator easy to wire and commission in floating point control sequences.
