Everyone,

In a motor spec what SLA stands for?

Regards,

RE: SLA

I've never seen that term.

SLA =Surge/Lightning Arrestors ???

Is it a typographical error and should be FLA = Full Load Amps?

RE: SLA

Smoking Load Amps  

Man that would be a strange motor for starting amps to be only a percentage of FLA..

How about Service factor amps  Maximum beyond-full-load breifly.. kinda of number ..Someone help me out here.

RE: SLA

Smoked

Sounds ok to me

Service factor (SF) of 110%
Service load amps (SLA = SF x FLA)

Have not heard of it before, but well, maybe......


RE: SLA

(OP)
Thank you all.

If it is so, why they have to mention it?
what would be technical interpretation for it.

Regards,

RE: SLA

surineman:

Where are you reading this? What else is mentioned along with it? Is there a value to SLA mentioned in the spec?

If it is spec written by some one, you need to ask who wrote it.

RE: SLA

service level agreement ?????

And if you don't know what that means, you are too young!

Seriously though, Service Load Amps. It is another seldom used way of adding the Service Factor into the rating. It was most often used for OEM motors where the motor mfgr was selling a standard design motor, knowing full well that the OEM was going to run it continuously into the service factor. I imagine they did it to try and avoid the service calls from people thinking the motor was running at too high of current ("over amping" as someone put it in this forum not too long ago!).

I haven't seen that used in a long time though. Is that an older motor?
