Description
The Hioki CT6280 AC Flexible Current Sensor is a high-accuracy, high-flexibility Rogowski-type current sensor for measuring AC current in tight spaces and around large busbars, cables, and multiple conductors. Unlike rigid clamps, the flexible sensor lead lets you wrap around conductors of varying sizes and shapes, making it ideal for industrial, power quality, and maintenance applications.
Hioki CT6280 AC Flexible Current Sensor – Maximum input current 4200 A AC (50–60 Hz), loop diameter 130 mm, cable length 800 mm, dual range 420 A / 4200 A, safety CAT IV 300 V / CAT III 600 V.
