Belimo NFXUP-S N4 Actuator
The Belimo NFXUP-S N4 Actuator is a high-torque, spring-return damper actuator designed for robust performance in demanding HVAC environments. Engineered with a NEMA 4 (IP66) enclosure, this unit provides superior protection against moisture, dust, and debris, making it an ideal choice for outdoor or wash-down applications. It features a universal power supply capable of handling 24-240VAC, eliminating the need for multiple SKUs on the job site. With a rated torque of 90 in-lb (10 Nm), it ensures reliable on/off control for dampers and valves requiring fail-safe operation. The integrated auxiliary switches allow for easy end-stop verification and position signaling. Built for heavy-duty mechanical spring return, the NFXUP-S N4 ensures consistent closure during power loss, maintaining system integrity in critical air handling unit (AHU) and ventilation sequences.
- Wide Voltage Range: The multi-voltage input (24-240VAC) simplifies field installation and reduces inventory overhead.
- NEMA 4 Rated Protection: Robust housing ensures long-term reliability in harsh environments and outdoor installations.
- High Torque Output: Provides 90 in-lb of torque for consistent operation of medium-sized dampers and valves.
- Integrated Fail-Safe: Mechanical spring return provides reliable equipment protection during power interruptions.
- Manual Override: Includes a manual crank for easy commissioning and emergency positioning.
Common Questions
What is the benefit of the NEMA 4 enclosure for this actuator?
The NEMA 4 rating indicates the actuator is protected against hose-directed water and dust, which is critical for rooftop units or areas where moisture infiltration is a concern.
Can the auxiliary switches be adjusted in the field?
Yes, the Belimo NFXUP-S N4 includes two built-in auxiliary switches that can be set to provide feedback at specific rotation points, improving sequence control.
Is this unit compatible with both clockwise and counter-clockwise fail-safe requirements?
Yes, the fail-safe direction (CW or CCW) is determined by the mounting orientation on the shaft, providing flexibility for different damper configurations.
