575/600V 3-Phase Motor Full-Load Amps

575/600V 3-Phase Motor Full-Load Amps lookup table with assumptions and boundary notes.

Scope

Motor current estimate only. Motor nameplate current, service factor, efficiency, power factor, voltage, and product data govern field application.

Lookup table

Estimate three-phase motor full-load current at 600 V from horsepower, efficiency, and power-factor assumptions.

Scroll sideways to keep row labels aligned with hidden columns.

Formula basis: amps = hp x 746 / (sqrt(3) x 600 V x efficiency x power factor), using rounded assumptions.

Notes
  • Check table values for preliminary lookup and arithmetic checks only.
  • Confirm equipment ratings, product markings, installation conditions, utility requirements, and the local authority requirements before design or field use.
