PM-3310 DetailPM-3310 is designed for electric power monitoring and load recording for single or three phase systems. It can be directly used in low voltage systems due to its wide range measurement (up to 1000A). PM-3310 can also maintain better than 1% (IEC-62053-21) accuracy even under low current condition (< 5A), thus it still can be used in middle to high voltage system. The unique features of PM-3310 including: Clip-on type CT, bi-directional measurement, long time load recording, and standard communication. Its compact size, easy installation, and low cost make PM-3310 suitable for modern electricity monitoring and load investigation.
