Its construction ensures durability and operational safety, making it a dependable component for electrical infrastructure.

Advantages

This fuse switch disconnector offers exceptional reliability due to its specialized design for busbar mounting, which simplifies installation and saves valuable space in electrical cabinets. The use of high-quality materials ensures consistent performance under load, while the 3-pole configuration provides comprehensive protection for three-phase systems.

Suitable for

Industrial power distribution panels
Commercial building electrical infrastructure

This device may not be suitable for applications requiring higher current ratings than 250A or for environments where the busbar spacing does not conform to the 40/60mm standard. It is also not intended for use in high-voltage transmission lines or outdoor environments without appropriate protective enclosures.

Key specifications

Rated current: 250A
Number of poles: 3
Mounting type: 40/60mm busbar system

Installation should be performed by qualified personnel in accordance with local electrical regulations. The device is mounted directly onto the busbar system, and cables are secured using the provided M10 screw terminals. Ensure that all connections are tightened to the specified torque to prevent loose contacts. Before operation, verify that the appropriate NH fuses are correctly inserted and that the housing is fully closed to ensure safe switching.

What to consider before purchase

Verify the current rating matches your circuit requirements
Confirm the compatibility of your busbar system (40mm or 60mm)
Ensure sufficient space is available in the distribution cabinet
Check that the M10 screw connections are suitable for your cable lugs

Usage recommendations: Regularly inspect the terminal connections for tightness and check the fuse status during routine maintenance to ensure continuous and safe operation of the electrical system.
