Belimo NMB24-SR Damper Actuator

Belimo NMB24-SR Damper Actuator delivers precise, modulating control for HVAC systems. This direct-coupled, non-spring return actuator provides reliable proportional control with a 95-degree rotation and 90 in-lb torque. It operates at 24 V AC/DC, 50/60 Hz, drawing 2.5 W running and 0.4 W holding, for efficient performance.

The rugged NEMA 2/IP54 enclosure ensures durability in demanding environments, with a shaft that accepts 1/2 to 1.05 inch diameters. A 3 ft 18 AWG plenum cable with a 1/2 inch conduit connector provides power and control connections. Rated for -22 to 122°F, it fits a wide range of HVAC installations. It is UL/ CE / CAN/CSA E60730 and ISO 9001 approved and includes an anti-rotation strap for secure mounting.
