C2M0500MQMJ Hammond 500VA Control Transformer, 240x480V to 120x240V, Molded Style

C2M0500MQMJ Hammond 500VA Control Transformer, 240x480V to 120x240V, Molded Style

Trying to figure out which control transformer fits your panel? If your equipment calls for a 500VA transformer that takes 240x480V power and steps it down to 120x240V, the Hammond C2M0500MQMJ is built for that job. A control transformer is simply a small transformer that supplies safe, low voltage power to the relays, switches, and controls inside an electrical panel, separate from the higher voltage main circuit.

This unit is a molded style transformer, meaning the coil is sealed to protect it from dust and moisture, and it is UL Listed, CSA certified, and CE marked. It handles high inrush equipment like relays, solenoids, and motor starters, and is backed by a lifetime warranty from Hammond.

Common Applications

• Industrial control panels
• HVAC equipment panels
• Machine and process automation systems
• Motor control centers
• Timers, solenoids, and relay circuits
• Battery storage system controls

Key Features

• Handles high inrush loads: Built to supply relays, solenoids, and motor starters without tripping offline.
• Sealed molded coil: Protects the internal windings from dust, moisture, and everyday wear.
• Copper windings: Keeps the output voltage stable and extends the life of the transformer.
• Easy grounding: A single ground point simplifies a safe, code-compliant install.
• Simple terminal block wiring: Both sides connect at a terminal block, no soldering or splicing.
• Lifetime warranty: Hammond covers this molded style transformer for as long as you own it.

FAQ

What does the C2M0500MQMJ do?
It converts 240x480V incoming power to 120x240V to safely run the control circuit in your panel, at a 500VA capacity.

How do I know this is the right part for my panel?
Check your existing transformer nameplate for a 500VA rating with 240x480V primary and 120x240V secondary voltage. If those match, this is the correct part.

Is this transformer safety certified?
Yes, it is UL Listed under file E50394, CSA certified, and CE marked.

Does it include a fuse block?
No, the standard C2M0500MQMJ ships without one. If you need a primary fuse block built in, look for the C2M0500MQMJ-1 version instead.

How much does it weigh, and will it need special shipping?
It weighs 10.6 lbs and measures 4.22 in H x 4.75 in W x 5.34 in D, so it ships as a standard parcel.

Where is it made?
Mexico.
