Bushing-type and bar-type current transformers
DESCRIPTION
For high requirements in railway and industrial technology at higher frequencies up to 50kHz. High-quality nanocrystalline core materials guarantee maximum transmission quality with low losses. Only UL-listed materials are used in full encapsulation with UL94-V0 material.
Current transformers for increased requirements such as in the railway sector or mobile applications. Robust housing designs with reliable mounting options for vertical or horizontal installation.
Advantages
- High reliability
- Non-critical in the event of overload currents
- Current transformers for precise current measurements
- Measurements in the frequency range 16 2/3 to -50kHz
- Use of nanocrystalline and high-quality cores
- High-quality wires in temperature class F (155°C), H (180°C)
- High-quality UL-listed insulating materials (e.g. UL94-V0)
- Safe electrically isolated primary and secondary circuits
- Robust housing designs (for horizontal/vertical mounting)
- Shock and vibration tests in accordance with DIN EN 61373
Variable connections: clamps, plugs, flat-cable plugs or cables
Wide range of housings with various push-through openings
