Electrical enclosure accessory Hager SBN263, AC input voltage 400 V

Hager SBN263 is an electrical enclosure accessory designed for systems that require an AC input voltage of 400 V. As a modular component from Hager, it integrates into distribution enclosures and switchgear assemblies to manage and route power within residential, commercial, or light industrial electrical panels. The unit is intended to be mounted alongside other modular devices to form part of a coordinated distribution solution.

Advantages

The accessory offers a compact modular form factor that simplifies installation and replacement within standardized distribution enclosures. It is engineered for compatibility with typical panel layouts and for reliable operation at 400 V AC input conditions. The design reduces the need for custom mounting solutions and helps maintain a tidy, serviceable arrangement of protective and switching devices in the enclosure.

Suitable for (tasks / use cases)

• Integration into electrical distribution panels requiring a 400 V AC input
• Residential main distribution boards and sub-distribution units
• Commercial electrical installations such as small offices and retail spaces
• Light industrial switchgear and power distribution assemblies

When it may not be suitable

This accessory is intended as a modular enclosure component and is not a standalone power source or consumer device. It may not be suitable where non-standard enclosure dimensions, specialized mounting rails, or bespoke switchgear layouts are used. Systems requiring voltages other than 400 V AC or where specific integrated protections or communication functions are mandatory may need a different product.

Key specifications

• Intended AC input voltage: 400 V
• Device type: modular enclosure accessory for distribution/switchgear assemblies
• Application environments: residential, commercial, light industrial distribution panels
• Mounting: modular mounting compatible with standard distribution enclosures

How to use

Install the accessory into the distribution enclosure according to the enclosure and device layout plan, ensuring it is mounted on compatible rails or mounting points. Connect incoming and outgoing conductors in compliance with local electrical codes, ensuring correct phase and neutral connections for a 400 V AC supply. Verify torque settings on terminals, secure covers, and perform functional and insulation tests before energizing the panel. Installation and final testing should be performed by a qualified electrician.

What to consider before purchase

• Confirm that the system uses a 400 V AC supply and that this accessory is compatible with the panel layout
• Ensure physical dimensions and mounting method match the target enclosure and rail system
• Check required current ratings and protective coordination with upstream and downstream devices
• Verify compliance with local electrical regulations and installation standards

Usage recommendations

Use this Hager accessory as part of a coordinated distribution setup. Coordinate protective devices and follow manufacturer mounting instructions. Routine inspection after installation helps ensure continued reliable operation in 400 V distribution systems.
