Product Information
Full details
The Hager KDN451E Quickbusbar Kamrail is designed for electricians and system integrators working with electrical distribution systems. Its key benefit is providing a fast, secure, and screwless connection for earth leakage switches using quickbusbar components. A potential caveat is its specific application for 4-pole earth leakage switches and its 1000mm length, which may not suit all installation sizes. This product facilitates efficient power distribution and connection within electrical enclosures.

FAQs
What is the primary purpose of the Hager KDN451E?
The Hager KDN451E is a junction rail fork used to provide a quick, secure, and screwless connection for 4-pole earth leakage switches within an electrical distribution system, utilizing Hager's quickbusbar technology.
What is the maximum current this kamrail can handle?
The rated continuous current (Iu) for the KDN451E is 80 A.
Can I use this kamrail for single-pole switches?
No, the KDN451E is specifically designed for 4-pole (3P+N) earth leakage switches.
What type of connection does it use?
It uses a fork-type electrical connection.
Is the kamrail insulated?
Yes, the product description indicates it is insulated.
What is the length of the KDN451E?
The length of the kamrail is 1000 mm.
Does this product require special tools for installation?
The quickbusbar system is designed for screwless connections, which typically do not require specialized tools beyond those for mounting the enclosure itself and potentially for cutting the rail if a shorter length is needed.
Troubleshooting
Kamrail does not connect securely to quickbusbar components.
Ensure the quickbusbar components are correctly seated and that the kamrail is aligned properly before attempting to connect. Check for any obstructions on the busbar or kamrail terminals.
Loose connection observed after installation.
Power off the system immediately. Re-seat the kamrail and ensure it has clicked firmly into place. Inspect the terminals of the connected devices for any damage.
Overheating at connection points.
Check if the connected devices' current ratings exceed the kamrail's 80 A rating. Ensure the cross-section of the conductors is appropriate (16 mm²). If issues persist, contact a qualified electrician for inspection.

Setup, Compatibility & Care
Setup: The KDN451E is designed for use with Hager's quickbusbar system. Ensure the main power is disconnected before installation. Slide the kamrail onto the quickbusbar components, ensuring a secure click for each connection point. The kamrail connects to the earth leakage switches by aligning the fork terminals and pushing them onto the corresponding busbar contacts.
Compatibility: This kamrail is specifically designed for 4-pole earth leakage switches that are compatible with the Hager quickbusbar system. It requires mating with other Hager quickbusbar components for a complete and safe installation. Verify compatibility with your specific switchgear and enclosure system.
Care: As a fixed component within an electrical enclosure, the KDN451E requires minimal user care. Ensure the enclosure remains clean and free from dust and moisture. Periodically, during routine electrical inspections, visually check that all connections remain secure and that there are no signs of damage or overheating. Do not use abrasive cleaners; a dry or slightly damp cloth can be used for cleaning the enclosure's exterior if necessary.
