18-3 Shielded VNTC Tray Cable, TFFN/PVC (Black, Red, Blue)

This 18 AWG, 3-conductor shielded VNTC (Vinyl Nylon Tray Cable) is a dual-rated Type TC-ER industrial cable. By combining the flexibility of TFFN conductors with the rigorous "Exposed Run" (ER) rating, this cable is designed for seamless transitions from cable trays to equipment without the need for protective conduit, all while maintaining 100% protection against electromagnetic interference (EMI).

Key Features of 18-3 Shielded VNTC (TC-ER)

• Exposed Run (TC-ER) Rated: This cable has passed the specialized UL 1277 crush and impact tests. Per NEC 336.10, it can be routed between a cable tray and the equipment it connects for distances up to 6 feet without continuous support or conduit, drastically lowering labor and material costs.

• Superior Noise Rejection: The overall aluminum foil-polyester tape shield (100% coverage) and tinned copper drain wire act as a barrier against EMI and RFI, ensuring that sensitive low-voltage signals are not corrupted by nearby power cables.

• Flexible TFFN Conductors: Utilizing TFFN (Thermoplastic Flexible Fixture Nylon) stranded conductors makes this cable significantly easier to manipulate in tight junction boxes and complex control panels compared to standard THHN.

• Industrial Durability: Featuring a flame-retardant, sunlight-resistant PVC jacket, this cable is resistant to moisture, heat, and oils. It is approved for direct burial and use in Class I, Division 2 hazardous locations.

Common Applications

• Remote Sensor & Transmitter Links: Connecting field instruments (flow, pressure, or temperature) to PLC input modules where shielding is required to prevent "signal jitter."

• Industrial Automation: Ideal for robotic cells and automated assembly lines where the cable must drop from an overhead tray directly to a machine-mounted control box.

• Motor Control Centers (MCCs): Used for auxiliary control circuits and monitoring signals that must pass through high-noise environments.

• Low-Voltage Power: Providing shielded power to small 24V or 120V peripheral devices such as fans, solenoids, or status indicators.

Technical Note: To ensure the shield functions as intended, the tinned copper drain wire should be properly terminated to a ground bus at the source end only. This prevents ground loops while allowing the shield to effectively drain induced interference. When utilizing the TC-ER rating, ensure the cable is secured and protected from physical damage in accordance with NEC requirements.
