Three-phase motor for industrial drives
The Dayton 4THZ5 is a three-phase general-purpose motor rated at 3/4 HP in a 56C frame. It runs on 230/460V AC at 60 Hz and suits equipment that needs continuous duty in fixed-speed applications. Buyers who require single-phase power or variable-speed control without an external drive will not be served by this unit.
Sustained-load behaviour with TEFC enclosure
The totally enclosed fan-cooled design dissipates heat while the motor runs at 1135 RPM under full load. Class F insulation and a 1.15 service factor support continuous operation at up to 40 °C ambient. Nominal efficiency is 75.5 percent, with full-load current of 3.0 A at 230 V or 1.5 A at 460 V.
Rigid-base C-face mounting and wiring notes
A rigid base and C-face flange allow direct coupling to gearboxes or pumps using standard 56C bolt patterns. Rotation is reversible for CW or CCW shaft direction. The motor carries CE, CSA and UL marks but has no built-in thermal protection, so external overload protection must be provided by the installer.

Questions about this item
How much heat and current does the 3/4 HP motor draw when running continuously at 1135 RPM?
At full load the motor draws 3.0 A at 230 V or 1.5 A at 460 V, operates in a 40 °C ambient limit and carries a 1.15 service factor for continuous duty.
What supply and mounting must I already have for this 56C frame motor?
You need a three-phase 230/460 V 60 Hz supply and a rigid base with a C-face mounting pattern that matches the 56C frame.
Will the 56C frame and CW/CCW rotation fit my existing gearbox and wiring?
The 56C frame with C-face mounting and reversible CW/CCW rotation matches standard 56C gearboxes and allows either rotation direction.
