UL Instrumentation Cable

300V Power-Limited Tray Cables — Overview

Construction

Soft annealed bare or tinned copper with

PVC flame retardant insulation and jacket.

Other insulation and jacket options are

available (see table below). Communication

wire included on all multi-pair/multi-triad

1000 and 3000 series part numbers, 22 AWG

(7x30) bare copper, orange PVC insulation.

Nylon rip cord included in all PVC/PVC

instrumentation cables.

Other Construction Options:

Armoring Capabilities

Belden also has the capability to protect

electronic, instrumentation and control cables

with interlocking or continuous armor and

smooth or corrugated protective metal tapes.

Application

Cable jackets are resistant to sunlight,

moisture and vapor penetration. PVC/PVC

constructions, with 3 conductors or more

and 20 AWG or larger, are suitable for

direct burial.

Unshielded

Twisted non-shielded pairs and triads

provide a minimal OD allowing greater tray

and conduit fill. Non-shielded instrument

pairs may be utilized when recommended

by the instrument manufacturer and used

in a metallic conduit.

Overall Shield

Recommended for use in instrumentation

applications where signals are transmitted

in excess of 100 millivolts except in areas

where high voltage and current sources

create excessive noise interference.

provides 100% coverage for maximum

shield effectiveness.

Individually Shielded and

Overall Shielded

Individually shielded pairs or triads with

an overall shield are recommended for

use in instrumentation applications where

optimum noise rejection is required.

Individual pair/triad shields are fully isolated

from each other and contain a separate

drain wire for grounding, to provide

maximum protection from crosstalk and

common mode interference. Cables with

an overall shield provide additional

electrostatic noise protection.

Specifications

Class 3 Circuits

approved for cable tray use in Class 1,

Division 2, hazardous areas and

non-hazardous areas, cable trays,

raceways, conduit and supported

by messenger wires.

ITC cables may carry up to 5 amps

at 150V, which is significantly greater

than that allowed for PLTC only cables.

ITC cables may also be installed in

specific applications, per the NEC,

in addition to those allowed for PLTC.

Test comparable to IEEE 383 -1974

(70,000 BTU/hr.) Flame Test.

IEEE 1202 and IEEE 383-2003 rated,

and meet ICEA T-29-520 Flame Test.

or 1-800-BELDEN-3.

PLTC-ER

As an option, Belden offers all PVC insulated,

PVC jacketed instrumentation cables, and

several other insulation and jackets, with a

PLTC-ER (Exposed Run) rating, formerly

referred to as Open Wiring.

Per NEC Article 725, a PLTC-ER rated cable

may be installed in an industrial establish-

ment between a cable tray and the utilization

equipment or device. A PLTC-ER rated cable

must meet the crush and impact require-

ments of UL Type MC cable By eliminating

the need for metal conduit and/or armor,

using a PLTC-ER rated cable results in

savings in both installation and maintenance.
