Belden 1057A 010, Power Limited Tray Cable 8PR 20 AWG 300V PVC, Black Jacket
Description
Belden 1057A 010 is a power limited tray cable for industrial control and instrumentation wiring in raceways, cable trays, and ducts. It features 8 twisted pairs of 20 AWG (7x28) BC - Bare Copper conductors plus 1 communication wire of 22 AWG (7x30) BC - Bare Copper, with PVC insulation. An overall Beldfoil® shield with 100% coverage and a black PVC outer jacket with ripcord support reliable signal performance and easier stripping. Ratings include 300 V (PLTC, CMG, AWM 2464), 150 V (ITC), and an operating temperature range of -30°C to +105°C, with Indoor/Outdoor and Sunlight Resistance suitability.
