Partial Spool of 3 Wire Shielded Cable 20 AWG | CL3R/CMR | 392 FT

Condition: Partial bundle, no box. Weight: 6.5 lbs.

Product Overview:

This shielded 20 AWG cable is designed for low-voltage applications, suitable for CL3R (Class 3 riser) and CMR (communications riser) installations. With a 75°C temperature rating, this cable can safely operate in environments requiring robust fire resistance and shielding to minimize interference. The markings suggest it is intended for temperature control systems or similar applications involving digital input/output connections.

Key Specifications:

• Gauge: 20 AWG
• Type: Shielded, riser-rated cable
  • CL3R: Approved for Class 3 low-voltage circuits in riser spaces.
  • CMR: Suitable for vertical installations through building risers.
• Fire Rating: FT4-certified for flame resistance.
• Temperature Rating: 75°C (167°F).
• Shielding: Protects against EMI (electromagnetic interference).
• Estimated Length: 392 feet (approximate).
• Weight: 6.5 lbs (partial bundle).

Markings on the Cable:
