Product Information
Full details
The Hager KBN Comb Rail (KBN663A) is designed for electricians and system integrators needing a reliable and efficient way to connect multiple single-pole circuit breakers in a 3-phase system. Its primary benefit is simplifying wiring and ensuring consistent power distribution for up to 12 devices. A key consideration is its specific suitability for devices with zero yellow and for use within series 12 automatic 1-phase installations.

How many devices can be connected to this comb rail?
This comb rail is designed to support up to 12 devices.
What type of electrical connection does it use?
It features a pin-type electrical connection.
Is this comb rail suitable for single-phase systems?
No, this comb rail is specifically designed for 3-phase electrical systems.
Can I use this with any type of circuit breaker?
It is suitable for devices with zero yellow and for Series 12 automatic 1-phase installations. Always confirm compatibility with your specific circuit breakers.
What is the conductor size it is designed for?
The comb rail is designed for conductors with a cross-sectional area of 10mm².
Can it be used with a residual current device (RCD) or ground fault circuit breaker?
Yes, it can be combined with a ground fault circuit breaker for added safety.
Troubleshooting
No power to connected devices
Verify that the main power supply is connected and active. Check that the comb rail is securely connected to the incoming power source and that all connected devices are properly seated and engaged.
Overheating of the comb rail
Ensure the total current load does not exceed the 63A rating. Check for loose connections on the comb rail or connected devices, as loose connections can cause increased resistance and heat. Verify that the conductor size (10mm²) is appropriate for the load.
Difficulty connecting devices
Ensure the devices being connected are compatible with the KBN series and the pin-type connection. Make sure any protective covers are removed and that the device is aligned correctly with the comb rail terminals.
Pros and Cons

- Not suitable for non-3-phase applications.
Setup, Compatibility & Care
Setup: The KBN663A comb rail is designed for straightforward installation within compatible electrical enclosures. Ensure the enclosure has adequate space for the rail and the connected devices. Mount the rail securely, then attach the circuit breakers or other compatible devices using their designated connection points.
Compatibility: This comb rail is specifically designed for 3-phase power distribution and is suitable for devices with 'zero yellow' (this refers to a specific terminal or configuration, consult electrical diagrams for precise application). It is intended for use within Series 12 automatic 1-phase installations. Always verify compatibility with the specific circuit breakers and other components being used.
Care: To maintain optimal performance and longevity, keep the comb rail and surrounding electrical components clean and free from dust and debris. Periodically inspect connections for any signs of corrosion or loosening, especially in environments prone to moisture or vibration. Ensure that the rated continuous current of 63A is not exceeded.
