Questions for: A.O. Smith Century 1.0 HP Thru-Bolt 48Y Motor - BN25V1

Got a Question?

What is Service Factor?
Reply

A Answered on 1/11/2012 by InyoPools Product Specialist Patrick P.

Service Factor(SF) is a multiplier that when multiplied by the horsepower of the motor indicates the total permissible horsepower loading that may be carried when the motor is operating at rated voltage and frequency. The most important thing to remember when replacing a motor is that the replacement motor's horsepower times its service factor must be equal to or greater than the original motor's horsepower times its service factor. The Service Factor rating can be found on the motor label. See Step 4 of our How to Read a Pool Motor Label guide.

Can an on/off switch be added to this motor? My motor is hardwired into my house circuit box and it isn't convenient to run up and down every time I need to turn off the motor. Is there a motor or system that does come with a switch?

Hi, Sharla. This motor does not come with the On/Off Switch - 18374501. The 1 HP w/ Switch - SPX1510Z1XE comes with the On/Off Switch.

Hi, Gary. Some motors have a special (SPL) HP rating based on the pumps application. The SPL rating is different from the motors true horsepower.

Is this a suitable replacement for an AO Smith 0-177894-24? I have attached a picture of the very old one that came with the pool when we bought our house.
