The Mersen MULTIVERT NH1 strip fuse switch disconnector is a professional-grade solution for power distribution and circuit protection in low-voltage switchgear systems. Designed for NH1 size fuses, this unit supports a rated current of 250A and is optimized for installation on busbar systems with 185mm spacing. The 3x1P configuration provides individual phase control, while the integrated V-clamps ensure robust and reliable electrical connections for demanding industrial environments.

Advantages

This switch disconnector offers exceptional reliability and safety for electrical infrastructure. Its compact strip design allows for efficient space utilization within electrical panels, facilitating easier installation and maintenance. The use of high-quality materials ensures long-term durability and consistent performance under load. Furthermore, the V-clamp connection system minimizes contact resistance and enhances the overall stability of the electrical circuit, providing peace of mind for critical power distribution tasks.

Suitable for

• Industrial electrical panels and switchgear
• Low-voltage power distribution networks
• Protection of electrical circuits using NH1 fuses
• Systems requiring 185mm busbar spacing

When it may not be suitable

This device is not intended for use in high-voltage applications or environments exceeding its rated current capacity of 250A. It is also not compatible with fuse sizes other than NH1 or busbar systems that do not adhere to the 185mm spacing standard.

Key specifications

• Rated current: 250A
• Fuse size: NH1
• Busbar spacing: 185mm
• Configuration: 3x1P
• Connection type: V-clamps

How to use

Installation should be performed by qualified personnel in accordance with local electrical regulations. The unit is mounted directly onto the 185mm busbar system. Ensure that the power supply is disconnected before installation. Insert the NH1 fuses into the designated slots and secure the electrical cables using the V-clamps, ensuring they are tightened to the manufacturer's specified torque to prevent overheating. Once installed, the switch can be operated to safely disconnect or connect the circuit as required.

What to consider before purchase

• Verify that your busbar system supports 185mm spacing.
• Ensure the 250A current rating meets your circuit requirements.
• Confirm that your system utilizes NH1 size fuses.
• Check available space in your electrical panel for the strip design.

Usage recommendations

Regularly inspect the V-clamp connections for tightness and check for any signs of thermal stress or discoloration during routine maintenance to ensure continued safe operation.
