TFFN Tray Cable - Unshielded, Type TC 90° C Dry - 75° C Wet - NEC® Article 340 - 600V

TFFN conductors use thin PVC insulation with a protective nylon sheath, which helps create a compact cable construction.

Type TFFN conductors combine PVC insulation with a tough nylon outer covering applied directly over the insulation. This construction helps reduce the amount of insulation material required around each conductor compared with some other cable designs. The resulting smaller overall diameter can be useful where tray fill, conduit space or equipment routing is limited.

The nylon sheath provides added mechanical protection over the PVC conductor insulation.

Each conductor in this TFFN tray cable uses 90°C PVC insulation covered by a tough nylon sheath. The nylon layer helps protect the underlying insulation during handling, pulling and installation while allowing the conductor construction to remain relatively compact. This PVC-and-nylon combination is one of the defining characteristics of TFFN wire.

Yes, it may be used in certain Class I, Division 2 locations when installed in accordance with applicable NEC requirements.

This Type TC cable is identified for use in Class I, Division 2 hazardous locations under the applicable NEC provisions referenced by the manufacturer. Suitability still depends on the specific installation, equipment classification and local electrical requirements, so the complete system should be reviewed before specifying cable for a hazardous area.

Unshielded cable is generally appropriate when electromagnetic interference is not a significant concern for the circuit.

Shielding is typically added when sensitive signals may be affected by electrical noise from motors, drives, switching equipment or other nearby conductors. An unshielded TFFN tray cable can be a simpler and more economical option for power and control circuits where interference protection is not required by the system design. The electrical environment and signal sensitivity should be considered before deciding between shielded and unshielded constructions.

Direct-burial approval allows the cable to be used underground without requiring a raceway in applications where the installation permits it.

UL listing for direct burial gives designers and installers another routing option when portions of a control or power circuit must travel underground. This can simplify certain industrial or facility installations by eliminating the need for conduit along every underground section, provided the installation complies with applicable electrical codes and physical-protection requirements. The cable on this page is UL Listed for direct burial.
