ABB ES300-9643 Current Transducer

ABB ES300-9643 Current Transducer is a bolt-on, through-core current sensor designed to monitor a single primary conductor with a nominal rating of 100 A. It is powered from a 24 V DC supply and provides a secondary current output rated at 150 mA, suitable for feeding measurement or control electronics in industrial panels and switchgear. The unit uses a three-pin connection and is intended for bolt-on installation with a through-hole for the primary conductor, enabling easy integration in limited spaces. It supports measurement of DC, AC, or pulsating currents while maintaining isolation between primary and secondary up to 3 kV (dielectric strength 50 Hz, 1 min), a key safety feature for panel-mounted monitoring. This model is part of ABB’s ES300 family of current sensors, commonly used for motor control, voltage/current monitoring, and energy-management tasks in industrial automation.
