KECA 250 B1

For dynamic current measurement (protection purposes) the ABB sensors KECA 250 B1, fulfil

requirements of protection class 5P up to an impressive value reaching the rated short-time

thermal current I

(31.5 kA). With KECA 250 B1 sensors, measuring class 0.5 is reached for

continuous current measurement in the extended accuracy range from 5 % of the rated

primary current I

not only up to 120 % of I

(as being common for conventional current

transformers), but even up to the rated continuous thermal current I

cth

(2 000 A). That

provides the possibility to designate the corresponding accuracy class as 5P125, proving

excellent linearity and accuracy measurements.

Technical parameters

– Continuous thermal current 2 000 A

– Rated primary current 250 A / 150 mV at 50 Hz or 250 A / 180 mV at 60 Hz

– Accuracy class 0.5 / 5P125
