I am using a allen bradley motor circuit protector (140M type) on a 1.5 hp motor listed at 3.0 amps. The short circuit setting is adjustable from 4 - 6.3 amps.
What is the maximim I can set this device?
Do I treat this like a dual element fuse in Table 430.52 and set at 175% of motor fla or can I set at 6.3 amps?
