• Terminals are brass studs No. 10–32 with one lock washer, flat washer, and regular nut
• The core and coil assembly is encased in a thermoplastic shell and filled with resin
• It is desirable to use a 1.6 amp fuse in the secondary to protect the transformer
• The M-0404 is primarily intended to transform 69 Vac control voltages to 120 Vac for operation with most Load Tapchanger controls
• Alternately, it may be useful (at reduced VA capabilities) of transforming 208 Vac nominal control voltage to 120 Vac by reversing the primary and secondary connections
• Each transformer includes two plastic terminal covers
• Approximate weight: 7.75 lbs
