Three-Phase Motor for Industrial HVAC
The Dayton 2NKX4 is a 1 HP three-phase motor built for general-purpose HVAC controls. It operates on 230/460V AC at 50/60 Hz with a nameplate speed of 1755 RPM. The steel frame carries a totally enclosed fan-cooled enclosure rated for continuous duty in ambient temperatures up to 40 degrees C.
Frame 143-5T/56HZ Fits Standard Mounts
A rigid base and the 143-5T/56HZ frame dimensions allow direct replacement on existing mounting patterns. Dual-voltage windings accept 230V or 460V supply with full-load currents of 3.0 and 1.5 amps respectively. Class F insulation and a 1.25 service factor provide margin for sustained operation without additional thermal protection.
Replaces Failed Single-Speed Units
This motor suits installations that need a direct drop-in for a worn single-speed three-phase unit of the same frame and voltage. The 85.5 percent nominal efficiency and ball bearings reduce long-term energy cost compared to older lower-efficiency designs. It is not for applications requiring variable-speed control, integrated thermal overloads, or single-phase power.
