HTB 300-P

Current Sensors Overview

The LEM HTB 300-P is a board-mount current sensor utilizing open-loop Hall effect technology for precise AC and DC current measurement. It features a single channel with bidirectional capability and a primary current rating of 300A. The device employs a single pass-through conductor design, allowing the measured conductor to pass directly through the sensor aperture without additional wiring modifications. This configuration supports efficient integration into power electronics systems requiring isolated current monitoring.
