Product information

Description

The Mersen MULTIBLOCK NH2 is a professional-grade 3-pole fuse switch disconnector engineered for high-current electrical distribution systems. Rated for 400A applications, this device provides a reliable solution for circuit protection and manual disconnection. Its robust design is specifically optimized for secure rail mounting, ensuring stability and ease of integration within industrial switchgear panels and electrical cabinets.

Advantages

This fuse switch disconnector offers exceptional operational safety and durability in demanding environments. The construction utilizes high-quality materials that withstand thermal stress and mechanical wear, ensuring long-term reliability. Its design facilitates efficient maintenance and quick fuse replacement, which minimizes downtime in critical infrastructure. Furthermore, the compact footprint allows for space-saving installation without compromising on performance or safety standards.

Suitable for

  • Industrial electrical distribution boards
  • Power supply systems for manufacturing facilities
  • Protection of motor circuits and heavy machinery
  • Main power distribution panels in commercial buildings

When it may not be suitable

This device is not intended for use in low-current residential applications where smaller fuse sizes are required. It is also not suitable for outdoor environments unless housed within an appropriately rated IP-protected enclosure to prevent exposure to moisture and environmental contaminants.

Key specifications

  • Number of poles: 3
  • Rated current: 400A
  • Fuse size compatibility: NH2
  • Mounting type: Rail mounted
  • Application: Industrial electrical distribution

How to use

The device should be installed by a qualified electrician onto a standard mounting rail within a distribution panel. Ensure that the incoming and outgoing power cables are properly sized and securely terminated according to local electrical codes. Once installed, the fuse switch disconnector allows for the safe insertion and removal of NH2 fuses. To disconnect the circuit, pull the handle to the open position, which physically isolates the load from the power source.

What to consider before purchase

  • Verify that the 400A rating matches your circuit requirements.
  • Ensure the mounting rail configuration is compatible with the unit dimensions.
  • Confirm that your system utilizes NH2 size fuses.
  • Check that the installation environment meets the necessary safety and enclosure standards.

Usage recommendations

Always ensure the circuit is de-energized before performing any maintenance or replacing fuses. Use appropriate personal protective equipment when operating high-current switchgear to ensure maximum safety.
