  • C-face rigid base mounting enables direct coupling to pumps and gearboxes
  • Class F insulation rated for 40 °C ambient ensures reliable thermal performance

Washdown Motor for Food-Grade Lines

The Dayton 1TRZ5 is a three-phase washdown motor rated at 1-1/2 hp and 1750 RPM. It operates on 230/460 VAC supply and fits a 56HC frame with C-face rigid base mounting. The totally enclosed non-ventilated steel enclosure suits horizontal installations in wet or sanitary environments.

Thermals and Continuous Duty

Insulation Class F supports a maximum ambient temperature of 40 degrees Celsius. The motor carries a 1.0 service factor and runs continuous duty at 60/50 Hz with no built-in thermal protection. Full-load current draws 4.3 amps at 230 VAC and 2.1 amps at 460 VAC.

Replaces Standard Open Motors in Wet Zones

This unit upgrades from open or ventilated motors that cannot withstand regular washdowns. The sealed enclosure and steel frame resist water ingress and corrosion where standard designs fail. Buyers needing integrated thermal overloads or variable-speed feedback should look elsewhere.

Questions about this item

How do I mount the 56HC frame C-face motor and wire it for 230 V or 460 V three-phase?

Bolt the rigid base horizontally, align the C-face flange with the driven equipment, and connect the nine leads per the nameplate diagram for 230 V (4.3 A) or 460 V (2.1 A) three-phase supply.

What maintenance does the totally enclosed non-ventilated washdown motor need over its service life?

Inspect shaft seals and bearing condition periodically; relubricate bearings if fitted with grease fittings, and verify the epoxy paint and stainless hardware remain intact against water ingress.

At what point does the 40 °C ambient limit or Class F insulation become the limiting factor during continuous duty?

Sustained operation above 40 °C ambient or with restricted airflow will cause winding temperature to reach the Class F limit first, reducing insulation life before the 1.0 service factor is exceeded.
