FAQs
Installation starts with confirming the device is the correct NH size (00) and that the mounting plate is compatible. Mount the disconnector onto the plate, connect conductors within the 4-95 mm² range to the box terminal, and route cables via the top/bottom outlets. Ensure clamps and copper paths align with the 13x13 mm area for secure electrical contact and minimal resistance.
Key specs include a rated operating current of up to 160 A, a rated operating voltage of 690 V AC (3~), and 3 poles. It uses a box terminal connection with a conductor range of 4–95 mm². The device is designed for mounting plate assemblies and complies with IEC/DIN EN 60 947-3 safety standards, with UL 94 rated polyamide material.
Yes. The 3-pole design, high current rating, and top/bottom cable outlets support reliable fault isolation and flexible wiring in control panels. Its mounting plate compatibility simplifies modular enclosure designs, while electromechanical fuse monitoring provides proactive protection and clear status indication for motors and loads in automation environments.
The unit is tested to IEC/DIN EN 60 947-3 electrical safety standards and uses UL 94 flame-rated materials, improving safety within enclosures. It also aligns with ETIM EC001040 and ECLASS 27371401 classifications, aiding procurement and cross-reference in technical catalogs.
Each pack weighs about 1.18 kg, with copper weight at 0.15 kg per piece. The electromechanical fuse monitoring and reliable isolation reduce downtime and maintenance costs, while the mounting plate compatibility accelerates installations. These factors contribute to a lower total cost of ownership in high-availability power distribution applications.
