safety disconnect

[trop920]

I have a three phase 600v 60amp disconnect that needs to be replaced. Can I use a 240v 60amp in its place. The equiptment is three phase 240v motor. If not why. Thank you

Welcome to the forum.

Provided that the 240 volt disconnect meets the requiremetns of 430.110, I see no reason why you could not use a 240 volt rated disconnect for a 240 volt motor.

As Chris states, as long as it's properly rated, no problem. With many manufacturers a 600v disconnect is only available as "Heavy Duty", whereas a 240v is available as "Strandard" or "Heavy Duty". You might want to keep that in consideration from an application standpoint.
