📝 Description

Used product.
Original ABB ES500C current transducer, identified by the markings on the housing: ES500C, code 10140153, and the specifications IPN 500 A – 600 V – VA ±12…±24 V.
This is a closed-loop Hall effect current sensor designed to measure direct, alternating and pulsed currents while maintaining galvanic isolation between the primary power circuit and the secondary measurement circuit.
The conductor being measured passes through the sensor's central opening. The device generates a secondary signal proportional to the detected current, suitable for compatible electronic control, monitoring and regulation circuits.
The construction includes an insulating housing, an opening for the primary conductor, a mounting flange and a secondary electrical connector.
