How To Size Nema Motor Starters. With nema use the voltage and hp rating. Hp at 230 v, ac.
Sizing an iec starter of the same type requires knowing the motor load, the duty cycle and full load current. All starters are shipped with an interposing relay as standard. Please use the chart as a guide when ordering heaters.
This Number Reflects The Same Mounting And Shaft Information Between Different Manufacturers In Order To Be Consistent.
Since nema frame size refers to mounting interfaces only, it has no direct bearing on the motor body diameter. 2 only available on an56 reversing starters. Nema and discussed the basics of a motor starter.
Specifying And Sizing Motor Starters.
Sizing an iec starter of the same type requires knowing the motor load, the duty cycle and full load current. To select a nema starter only horsepower and voltage are needed. There are four basic motor control options available:
A N 1 9 A N 0 A 5E 005 Device Type A = Starter C = Contactor Contactor.
Coil voltages are typically available in 24v, 120v, 208v, 240v, 277v, 480v, and 600v varieties. The magnetic motor starter is also offered in different types of enclosures, depending on the environment in which the equipment will operate. Otherwise for “normal” cases with iec use the flc from the nec chart and pick based on the voltage and the ac3 column in the catalog.
The Ratings For These Devices Fall In Between The Ratings Of Normal Nema Sizes, Allowing The User To More Closely Match The Motor Control To The Actual Application.
Hp at 480/575 v, ac. The following table shows motor matched sizes. Starters are available as open and enclosed with electronic overload protection.
Basic Contactors, Traditional Starters, Manual Motor Starters, Or Combination Starters.
In previous blog posts, we talked about the differences between iec vs. These nema sizes classify a magnetic motor starter by voltage and maximum horsepower. (1) this rating is for the size 6 contactor coil only.
