Eaton C0050E2AFB – Frequently Asked Questions
1) What secondary voltage does the Eaton MTE control transformer put out for a control circuit?
The MTE Series steps down to a 120/115/110V secondary, which is what standard control circuits, relays, contactor coils and pilot devices in a panel run on. Primary side is dual-voltage, so the same unit covers two supply voltages depending on how you land the taps.
2) What is the difference between the Eaton C0050E2AFB and the C0050E5EFB?
Both are MTE control transformers with the same 120/115/110V secondary; the difference is the primary tap arrangement. The C0050E2AFB carries E2 primary taps (the same E2/E4 tap family as the C0075E2AFB and C0100E4DFB), and the C0050E5EFB carries E5 primary taps. Pick the one whose primary taps match your incoming supply voltage.
3) Does the Eaton MTE transformer come with a primary fuse block, or do I have to add one?
A factory-mounted two-pole primary fuse block is part of the build, sized for non-rejection type fuses. That means you do not need to find panel space for a separate fuse holder on the line side, but the fuses themselves are a separate item and must be non-rejection style to seat in the block.
4) Will an Eaton MTE control transformer work on a 50Hz machine imported from overseas?
Yes. The MTE Series is rated for 50/60Hz operation, so it runs on either a North American 60Hz supply or a 50Hz system on imported machine tools and OEM equipment.
5) Is the Eaton MTE control transformer approved for use in Canada?
It is cUL Certified and RoHS Compliant, which covers it for code-regulated installations on both sides of the border. Those are the only listings stated for the MTE Series.
6) Can this Eaton transformer handle a hot, dusty or damp machine shop environment?
The MTE is epoxy-encapsulated, which seals the windings against moisture and airborne contamination in shop and plant environments. It uses a 130 degree C insulation system with a 55 degree C temperature rise rating under load.
7) Can I use an Eaton MTE control transformer to retrofit an existing control cabinet?
That is one of its stated uses, along with motor control centers, starter enclosures, machine tool and automation control circuits, and OEM equipment needing stepped-down control power. For a retrofit, match the primary tap version (E2/E4 or E5) to the supply already feeding the cabinet and confirm the existing control devices run on 120/115/110V.
8) Are the windings on the Eaton MTE copper or aluminum?
Copper. Copper windings run cooler at a given load and hold terminal torque better over time than aluminum, which is why they are specified on control transformers feeding contactor coils that cycle constantly.
9) How do the wiring terminals attach on the Eaton MTE control transformer?
Terminals are molded into the encapsulated body rather than mounted on a separate strip, so there is nothing to loosen or shift when you land field wiring. The core is built from silicon steel laminations to hold down core losses on a circuit that sits energized all day.
