ABB HBO Current Sensor

An open loop current sensor, accurate and reliable, available in ranges from 100 A to 600 A nominal current.

Sensor for AC, DC or pulsating current measurement. The HBO range is based on Open Loop Hall Effect technology with galvanic insulation between the primary and secondary circuits. Plastic case and insulating resin are self-extinguishing. Fixing holes in the case moulding for two positions at right angles. Direction of the current: A primary current flowing in the direction of the arrow results in a positive secondary output voltage on terminal VS. Primary connection: Hole for primary conductor. The temperature of the primary conductor in contact with the case must not exceed 100 °C. Secondary connection: Molex HE14 with 4 pin connector.
