Details for NMB24-3
Damper Actuator | 90 in-lb | Non-Spg Rtn | 24V | On/Off/Floating Point
For on/off and floating point control of dampers in HVAC systems. Actuator sizing should be done in accordance with the damper manufacturer’s specifications.
The actuator is mounted directly to a damper shaft up to 1.05" in diameter by means of its universal clamp, 1/2” self-centered default. A crank arm and several mounting brackets are available for applications where the actuator cannot be direct coupled to the damper shaft.
The actuator is not provided with and does not require any limit switches, but is electronically protected against overload. The anti-rotation strap supplied with the actuator will prevent lateral movement.
The NMB(X) series provides 95° of rotation and a visual indicator indicates position of the actuator. When reaching the damper or actuator end position, the actuator automatically stops. The gears can be manually disengaged with a button on the actuator cover.
The NMB(X)24-3… actuators use a sensorless brushless DC motor, which is controlled by an Application Specific Integrated Circuit (ASIC). The ASIC monitors and controls the actuator’s rotation and provides a digital rotation sensing (DRS) function to prevent damage to the actuator in a stall condition. Power consumption is reduced in holding mode.
Add-on auxiliary switches or feedback potentiometers are easily fastened directly onto the actuator body for signaling and switching functions.

An Affordable Choice
Belimo has a line-up of great products that are just right on the budget. Aside from this, quality is also guaranteed. They have more advanced safety features than the other similar products out there. Their visual indicator without a doubt, the most useful feature we have come across in any similar production. The design is also well done as well. We would highly recommend this to anyone working in similar industries as ours to get this easy-to-install product.
Powerful tool in a small form factor
This damper actuator is finely designed for its price and size. Very competitive compared to others of its type out there in the market. It has safety features such as overload failsafe, anti rotation straps to secure mounting and a visual indicator. On top of being a safety feature the visual indicator is also very useful for inspection and troubleshooting. Being able to see the exact position of the damper without having to take the device apart during breakdowns saves hours off of repair times. The gears on the actuators can also be manually halted with a press of a button from the outside. I mean, they really did well in designing the product. Getting devices such as these to work for you in the way it does makes you feel somewhat appreciated. It’s like someone out there is actually thinking of ways to make your job easier.
Easy to install and operate
The NMB24-3 can be mounted several different ways with different types of mounting brackets. It even comes with an anti rotation strap to make sure that the actuator is secured in place during operation. It saves a lot of time from looking for a perfect fit and is financially efficient too. The device is also electronically protected from any overload situations. The microprocessor on this device actually prevents it from getting any further damage during a breakdown with its DRS feature. Great design and manufacturing by Belimo. We are happy with the choice we made. It’s one of the best of it’s kind in the market.
