12 AWG 3C Shielded VFD Cable W/ 3 #16 Grounds

“12/3 Shielded VFD Cable is a specialized, 600V TC-ER / 1000V Type Motor Supply rated solution engineered to deliver clean power from Variable Frequency Drives to demanding industrial motors. Featuring a unique 3-conductor configuration with symmetrical grounding, this heavy-duty 12 AWG cable utilizes a premium dual-layer shield (aluminum foil tape and tinned copper braid) along with moisture-resistant XLPE insulation to suppress intense EMI/RFI noise, handle severe high-frequency voltage spikes, and completely eliminate the need for costly termination kits. Encased in a rugged, direct burial rated PVC jacket, it provides maximum longevity in the harshest industrial and outdoor pump environments.”

Why Professionals Choose 12/3 Symmetrical Ground VFD Cable

Standard electrical wire acts like an antenna under high-frequency VFD switching, bleeding noise into control circuits and destroying motor bearings. This 3-conductor symmetrical layout is engineered to eliminate those failures entirely:

• Symmetrical Ground Balance: Rather than one large ground, this design splits the ground path into three individual #16 AWG conductors nestled symmetrically between the phase conductors. This cancels out common-mode stray voltage currents, protecting motor bearings from electrical pitting.

• 100% EMI/RFI Noise Suppression: Combines a 100% coverage aluminum/mylar/aluminum foil shield with a heavy tinned copper braid. This dual-layer defense seals in high-frequency switching noise before it can glitch nearby PLCs, sensors, or Ethernet lines.

• No Termination Kits Required: Unlike some alternative VFD configurations, this highly efficient 3-conductor layout is engineered to connect cleanly directly to terminals without requiring expensive, labor-intensive termination kits.

• Exposed Run (TC-ER) Rated: Complies with UL 1277 for direct-run installation from the cable tray directly to the motor housing, completely saving the high material and labor costs of running rigid metal conduit.
