SPECIFICATION
Design Number:
50 PAIR #24 AWG UTP CAT 3 PLENUM
HT32940
DESCRIPTION UNSHIELDED TWISTED PAIR (UTP) CATEGORY 3 CABLE FOR USE IN BACKBONE CABLING SYSTEMS PER ANSI/TIA-568-C. THE CABLE CONSISTS OF #24 AWG SOLID BARE COPPER INSULATED CONDUCTORS, ASSEMBLED INTO TWISTED PAIRS, WITH A RIPCORD, UNDER AN OVERALL JACKET.
Jacket Insulation
THE CABLE IS PLENUM RATED FOR USE IN AIR HANDLING DUCTS AND SPACES IN ACCORDANCE WITH ARTICLE 800 OF THE NATIONAL ELECTRICAL CODE (NEC). THE CABLE IS UL (USA) & cUL (CANADA) LISTED FOR THIS APPLICATION BY PASSING NFPA 262 (FT6 OR PREVIOUSLY UL 910 STEINER TUNNEL) TEST.
