JRFS-XXXR SERIES - 1

JRFS-XXXR SERIES ULTRA FLEXIBLE ROGOWSKI COIL CURRENT TRANSFORMER The flexible Rogowski coil of high-accuracy split-core current transformers offer significant installation advantages overthe general split-core CT’s because oftheir light weight, wide current range (10- 5000+ Amps), mechanical flexibility for mounting in tight guarters and easy placement around cable bundles or large busbars. Offered in 3.15", 4.52", 7.08" and 11.81" windowsizes, the JRFS-R series are the most accurate Rogowski Coil in submetering. The JRFS-R series are certified by UL 2808 Listed (XOBA) to meet the new regulation about Power monitoring eguipmentthat may be used in accordance with NEC 312.8(B). These new Revenue-Grade flexible Rogowski coil CT complying IEEE/ANSI C57.13 class 0.6 accuracy standard may be used with remotely mounted devices certified as Energy Usage Monitoring Systems (FTRZ) by UL. Features ■ Quick & simple install with plug & play type ■ Safe 120 mV secondary output (60Hz) ■ Current range: 10 - 5000+ Amps ■ Accuracy standard: IEEE/ANSI C57.13 class 0.6 ■ UL/EN 61010-1 & UL 2808 Listed (XOBA, XOBA7) Option: Busbar mounting 1. Specifications ■ Coil length :30 cm- 300 cm ■ Window size : 80 mm - 300 mm ■ Cord diameter: 8±0.2mm ■ Weight: 150 - 500 g Specifications are subject to change without notice. www.hqsensing.com

5. Safety Notes A Caution : Danger Ahazard of electric shock, explosion, or arc flash ■ In order to guarantee safe operation of the CT, please read and understand the instructions thoroughly. For your reference, see NFPA 70E in the USA, or applicable local codes. Safe operation can only be guaranteed if the Rogowski coil CT is used for the purpose as intended and designed within the limits of the technical specifications. ■ Before servicing the CTs, turn off all sources of power and use a properly rated voltage sensing device to check if the power is off. ■ The flexible Rogowski coil CT...
