Belden Inc. 82777 877U500 Fire Shielded Cable 3pr 22AWG

Product Description

The BELDEN INC. 82777 877U500 is a fire-shielded solid instrumentation cable designed for signal and control wiring in demanding industrial and commercial environments. This cable features a 3-pair, 22 AWG solid conductor construction with FEP (fluorinated ethylene propylene) insulation, providing reliable flame resistance and low smoke characteristics. The FEP jacket stands up to elevated temperatures and harsh operating conditions, making this cable a dependable choice for critical instrumentation runs where fire safety compliance is a priority. Electricians and instrumentation technicians working in process control, building automation, and life safety systems rely on this cable type for stable, low-interference signal transmission.

This cable is suited for use in commercial and industrial facilities where fire-rated wiring is required by code. Typical applications include control loops, sensor wiring, and signal circuits in HVAC control systems, fire alarm infrastructure, and process instrumentation panels. The flame-resistant rating addresses requirements in installations where cable routing passes through areas subject to fire safety codes, including plenum and riser pathways where FEP-insulated cables are commonly specified.

Key Features

• 3-pair, 22 AWG solid conductor configuration for instrumentation and control signal use
• FEP insulation provides flame resistance and thermal stability at elevated temperatures
• Fire-shielded construction helps maintain circuit integrity in fire-rated installations
• Solid conductors support stable low-level signal transmission with minimal resistance variation
• Flame-resistant rating supports compliance with applicable fire and electrical codes

Compatibility

Designed as a fire-shielded solid instrumentation cable suitable for control and signal wiring applications in commercial and industrial systems requiring FEP-insulated, flame-resistant cable.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the NEC and any applicable local codes governing fire-rated and instrumentation wiring. De-energize all circuits before terminating or splicing. Avoid sharp bends that could damage the FEP jacket or deform solid conductors. Maintain proper separation from power conductors to preserve signal integrity.
