2.2.1 NOTES
2.2.1.1 The HP listing is for reference only. For proper selection use the current rating.
2.2.1.2 The fuses recommended are Class J time-delay type. This fuse is being suggested even
though it may not protect the SCR in an output shorted condition while braking. It will
protect the unit when starting to operate into a shorted output. In the case of a shorted
SCR, the fuse is there to clear the fault only.
2.2.1.3 The RMS AC line current is equal to : AC RMS = DC Amps x
√ Duty Cycle Assuming
10A motor, OP-STOP set at 300% current (30 A DC), free wheeling for 70% of the
cycle, then the AC current is 16A.
2.2.1.4 All OP-STOP models are built without cooling fans because they are short duty rated.
