Suitable for

• Industrial electrical distribution networks
• Low-voltage switchgear assemblies
• Power supply systems requiring 400A protection
• Applications utilizing 185mm busbar configurations

When it may not be suitable

This device is not intended for use in systems exceeding its 400A current rating or for applications requiring different busbar spacing than the specified 185mm. It is also not suitable for high-voltage installations or environments that fall outside the standard operating conditions for low-voltage switchgear.

Key specifications

• Rated current: 400A
• Number of poles: 3-pole
• Busbar system compatibility: 185mm
• Terminal type: 3xM12
• Application: Low-voltage distribution

How to use

The Mersen MULTIVERT NH2 should be installed by qualified electrical personnel in accordance with local safety regulations. The unit is mounted directly onto the 185mm busbar system. Ensure that all connections to the 3xM12 terminals are tightened to the manufacturer's specified torque to prevent overheating. Once installed, the fuse links are inserted into the switch body, and the handle mechanism allows for safe manual switching and isolation of the circuit.

What to consider before purchase

• Verify that your existing busbar system is exactly 185mm.
• Ensure the 400A rating matches your circuit requirements.
• Confirm that the switchgear cabinet has sufficient depth and clearance for vertical mounting.
• Check that the M12 terminal connections are compatible with your cable lugs.

Usage recommendations

Regularly inspect the terminal connections for tightness and check the fuse links for signs of wear or thermal stress to ensure continued safe operation of the electrical network.
