Electrical enclosure accessory Hager KJ100A — 71×44×97 mm, for 100 A 4-pole distribution

Hager KJ100A is a compact electrical enclosure accessory with dimensions 71×44×97 mm designed for use in 100 A four-pole distribution applications. It functions as a mounting or blocking element within distribution boards and switchgear, offering a space-efficient solution to organize and secure four-pole circuits in residential and light commercial installations.

Advantages

This accessory provides a small footprint while maintaining compatibility with 100 A four-pole distribution systems. Its compact rectangular form factor allows for tidy arrangement of components inside enclosures and contributes to safer separation or fixation of a four-pole module. The product is manufactured by Hager and is intended for reliable, standardized installation practices common to modern distribution boards.

Suitable for (tasks / use cases)

• Mounting or blocking of 4-pole 100 A circuit modules inside distribution boards
• Organizing space in small electrical enclosures where compact components are required
• Residential and light commercial electrical installations using 4-pole distribution
• Applications that require separation or mechanical support for multi-pole devices

When it may not be suitable

This accessory is intended specifically for 100 A, four-pole distribution arrangements and may not fit or be appropriate for panels with different pole counts, current ratings, or nonstandard mounting geometries. It is not a standalone protective device; electrical protection and isolation must be provided by appropriate circuit breakers or residual current devices according to installation requirements.

Key specifications

• Dimensions: 71 mm (width) × 44 mm (depth) × 97 mm (height)
• Intended use: 4-pole distribution, rated for 100 A systems
• Function: mounting / blocking element for distribution boards
• Typical application environment: residential and light commercial switchboards

How to use

Install the part inside the distribution board in the position required to support or block the target four-pole module, following the enclosure manufacturer’s layout and local electrical regulations. Ensure power is disconnected before installation. Fit the accessory to the intended mounting points and confirm that adjacent devices retain proper clearances and access. After installation, verify mechanical stability and that protective devices remain accessible and correctly aligned.

What to consider before purchase

• Confirm the accessory’s compatibility with the board layout and the four-pole equipment intended for use
• Verify required clearances, mounting geometry and available space inside the enclosure
• Check that the accessory meets local installation standards and integrates with chosen protective devices

Usage recommendations
