0–150A Current Range for Branch Circuits

Optimized for common medium and small current monitoring requirements.

Accurate matching for cabinet branch and equipment sub-circuits

The QD-14 series covers measurement ranges up to 150A, specifically targeting branch circuits and equipment sub-circuits. In industrial automation, while main power lines carry massive loads, the individual components—such as localized motor drives, heating elements, and auxiliary power feeds—typically operate within this medium-to-small current spectrum.

Φ4–15mm Aperture Options

Φ4, Φ8, Φ12 and Φ15mm apertures designed for compact wiring spaces.

Enhanced installation flexibility for thin cables and dense control panels

Space is a premium resource inside modern control panels. The QD-14 current sensor addresses this constraint by offering multiple aperture dimensions: Φ4mm, Φ8mm, Φ12mm, and Φ15mm. These varied openings allow the sensor body to closely match the specific conductor diameter at each monitoring point, which is particularly valuable in densely wired environments where cable sizes fluctuate significantly between auxiliary circuits and main equipment connections.

Clear Status Indication for Inspection

Power and operational status verified directly on the module body.

Streamlined maintenance for multi-point cabinet installations

Efficient maintenance is critical for minimizing downtime in industrial operations. The QD-14 is equipped with a clear local status indicator (PWR) that allows technicians to instantly verify the power and operating condition of the unit without requiring external testing tools. In complex control cabinets where dozens of sensors might be installed across various branches, this visual feedback is invaluable.
