ABB Mistral41W Surface Mounted Modular Distribution Board 1x18 Modules IP41 63A Class II with Solid Door

The ABB Mistral41W surface-mounted modular distribution board is a robust and reliable solution for managing electrical circuits in various environments. Designed to accommodate 18 modules in a single row, this unit provides a secure and organized housing for miniature circuit breakers, residual current devices, and other modular components. With its solid door and high-quality construction, it ensures both aesthetic integration into your space and protection for the internal electrical equipment.

Advantages

This distribution board stands out due to its Class II insulation, which provides an extra layer of safety by eliminating the need for protective earthing of the enclosure itself. The IP41 protection rating offers effective defense against solid objects and vertical water drops, making it suitable for indoor installations where basic environmental protection is required. The inclusion of screw-type N+PE terminals simplifies the wiring process, allowing for efficient and secure connections during installation. Its surface-mounted design facilitates easy access and installation on walls without the need for complex wall recesses.

Suitable for

• Residential electrical distribution systems
• Small commercial office installations
• Indoor environments requiring organized circuit protection
• Upgrading existing electrical panels in homes or small businesses

When it may not be suitable

This unit is not designed for outdoor use or environments exposed to significant moisture, dust, or harsh chemical conditions, as the IP41 rating does not provide protection against heavy water jets or fine particulate ingress. It is also not suitable for applications requiring more than 18 modules in a single row or for systems exceeding a 63A current capacity.

Key specifications

• Capacity: 1x18 modules
• Mounting type: Surface mounted
• Protection rating: IP41
• Rated current: 63A
• Insulation class: Class II
• Door type: Solid
• Terminals: Screw-type N+PE

How to use

The distribution board should be mounted on a flat, stable vertical surface using appropriate hardware. Once secured, the modular components can be snapped onto the internal DIN rail. Wiring should be connected to the provided N+PE screw terminals according to local electrical codes and the specific requirements of the circuit breakers being installed. Ensure that all connections are tightened to the manufacturer's specified torque to prevent overheating. The solid door should be closed after installation to maintain the integrity of the enclosure.

What to consider before purchase

• Verify that the 18-module capacity is sufficient for your current and future circuit requirements.
• Ensure the installation location is indoors and protected from direct water exposure.
• Confirm that the 63A current rating meets the demands of your electrical system.
• Check the available wall space to ensure the surface-mounted dimensions fit your intended area.

Usage recommendations: Always ensure that the electrical installation is performed by a qualified professional in accordance with local safety regulations. Periodically inspect the enclosure and connections to ensure they remain secure and free from damage.
