CURRENT MEASUREMENT DEVICE, CURRENT MEASUREMENT DEVICE FOR DISTRIBUTION BOARD AND DISTRIBUTION BOARD USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a current measurement device capable of improving measurement accuracy of load current including harmonic, a current measurement device for distribution board and a distribution board using the same.SOLUTION: A current measurement device 5 includes: a base plate 51; a coil 52; a measurement section 55 that measures a load current based on the output from the coil 52. The current measurement device 5 for distribution board is electrically connected between a pair of inputting leads 551 of the measurement section 55 and a pair of output terminals 521 of the coil 52 including a filter 58 for filtering signals of a frequency higher than a predetermined frequency (power source frequency).
