Their greatest advantage is the ability to install them without disassembling or cutting existing busbars and cables. Thanks to their split-core design, they can be easily mounted on already installed systems, significantly reducing working time and minimizing production downtime.
Lumel offers high-quality split-core current transformers that are ideally suited for industrial, energy, and building automation applications.
They are available in four mounting window size versions:
- 18.5 mm (compact versions)
- 32.5 mm (compact versions)
- 23 × 33 mm
- 85 × 54 mm
- 85 × 125 mm
- 82 × 162 mm
This range of sizes allows the transformer to fit a wide variety of busbar cross-sections, making them an extremely versatile solution.
Measurement Ranges:
- 150...500 A – compact versions, accuracy class 1
- 100...5000 A – full range of models, accuracy class 0.5 or 1
The external dimensions depend on the selected model.
Upon customer request, the transformers can be supplied with calibration certificates, allowing them to be used in installations requiring certified measurement accuracy.
