Dayton 48ZJ89 3-Phase Machinery Motor 2 HP 56H Frame 208-230/460V AC

SKU CH-6GGC-X44PB

A three-phase general-purpose motor delivers 2 HP at 3505 RPM with a 56H frame and dual-voltage 208-230/460V AC operation

  • Delivers 2 HP for demanding industrial tasks
  • Runs efficiently at 85.5% nominal efficiency
  • Operates on 208-230/460V AC three-phase power
  • Withstands heat up to 40°C ambient temperature
  • Fits standard 56H frame mounting configurations

Dayton 48ZJ89 Three-Phase Motor

The Dayton 48ZJ89 is a 2 HP three-phase general purpose motor built for industrial machinery. It suits maintenance teams and OEMs needing a reliable drop-in unit for pumps, fans or conveyors. The 56H frame and rigid base mounting match common industrial footprints. Continuous duty rating supports non-stop operation in demanding environments.

Steel Frame Totally Enclosed Fan Cooled Design

A steel frame and totally enclosed fan cooled enclosure protect windings from dust, moisture and debris. Ball bearings reduce friction and extend service life under heavy radial loads. The motor runs on 208-230/460 V AC at 60/50 Hz with full-load currents of 5.0 A and 2.5 A respectively. CW/CCW rotation flexibility simplifies installation alignment.

Upgrade from Single-Phase or Lower Efficiency Units

Replacing a single-phase motor with this three-phase unit delivers smoother torque and higher efficiency of 85.5 percent. The 1.25 service factor provides overhead for occasional overloads without tripping. Insulation class F and a 40 °C maximum ambient temperature suit harsh plant conditions. The jump is worth it when uptime and energy savings outweigh the cost of three-phase supply.

Questions about this item

What voltage range does the three-phase 208-230/460V AC motor support, and what full-load current does it draw?

The motor runs on 208-230/460V AC at 60/50 Hz and draws 5.0 amps at the low-voltage connection or 2.5 amps at the high-voltage connection.

What frame size and mounting type are required to install this 56H frame motor?

It uses a NEMA 56H frame with a rigid steel base, so the mounting surface must match the 56H bolt pattern and support the motor's weight.

How do you wire the dual-voltage terminals, and which step is commonly missed?

Connect the nine leads for either 208-230V or 460V per the nameplate diagram; the step often missed is reconfiguring the internal jumpers when switching between the two voltage ranges.
