Excel mill uses FUJI SW-03RM/3H, the part is marked SC-03(11 and
relay is Fuji HH52 PL.

I'm looking for cross reference to other manufacturers or an updated part number or a source for purchasing these parts.:drowning:

Replacing or sourcing a different make of contactor is not usually that difficult, from the original you need to know the amount of power contacts, 3 or 4, the number of auxilliary contacts and whether N.O. or N.C.
Whether an O/L is fitted and the current setting range.
What is the nature and current of the load, H.P. etc.
What is the coil voltage and whether the coil is AC or DC.
There are many makes available in the US that should fit the bill, Square D (Telemecanique) , Allen Bradley, just to name a couple.
Most of the compact DIN style come configurable with the aux and O/L as add on's

If it is the same as this, it is not a contactor but a very common relay, should be simple to sub a P&B (Tyco) or Omron etc.
