EASTRON ESCT-B Series is a big current 1/5A output split core current sensor designed to facilitate the installations in new or already existing net works. They may be installed without opening any cable or bus-bar circuit.
The ESCT-B Series support up to 6300A current, which is an ideal solution for big primary current situation and bus-bar installation. An internal precision resistor across the secondary winding of the CT provides a low safe voltage output. It can save time and the installation costs.
