Siemens GIB146.1U 3-point non-spring return actuator 24 VAC (90°)

Product Description

Siemens GIB146.1U is a 3-point non-spring return (NSR) electric damper actuator rated for 24 VAC control and 310 lb-in torque. It provides 90° nominal rotation for modulating or three-position control, with manual override, mechanical range adjustment, and a visible position indicator. The actuator includes precabled 18 AWG leads, synchronous motor technology, silicone-free gear lubrication, UL873 and cUL listing, and IP54/NEMA 2 enclosure for HVAC damper applications.

• 310 lb-in torque; 90° nominal (95° maximum) angular rotation; runtime 90 s at 60 Hz and 108 s at 50 Hz for 90°
• 24 VAC operation at 50/60 Hz with precabled 18 AWG leads (3 ft or 6 ft options) and synchronous motor technology
• Manual override, mechanical range adjustment, visible position indicator, silicone-free gear lubrication, UL873 and cUL listed, IP54/NEMA 2

Product Highlights

Electric NSR actuator for HVAC damper control with 310 lb-in torque, 24 VAC operation, 90° rotation, manual override, and IP54/NEMA 2 enclosure.
