FAQs
What is the maximum number of devices this busbar can connect?
The A9XAH257 has 57 modular spacings and a 45mm pitch, allowing it to connect up to 22 two-pole devices.
Can this busbar be used for three-phase systems?
No, this busbar is specifically designed for 2-pole single-phase systems.
What is the rated current for this busbar?
The rated permanent current (Iu) for this busbar is 100A.
What is the voltage rating of the A9XAH257?
The rated operational voltage (Ue) is 415V AC, and the rated insulation voltage (Ui) is 500V AC.
How do I ensure the busbar is installed safely?
Always ensure the main power supply to the distribution board is switched off and locked out before installation. Follow standard electrical safety procedures and ensure the busbar is fully seated and connections are secure.
Can I use this busbar with non-Schneider Electric devices?
While it might physically fit, Schneider Electric strongly recommends using this busbar only with the specified compatible Schneider Electric devices (iC60, iID, ISW-NA, iK60, iID K, ISW) to guarantee performance, safety, and compliance.
What is the 'Better World' status of this product?
Yes, this product is marked as a 'Better World Product' and is verified as 'Green Premium', indicating its environmental performance and compliance with regulations like RoHS.
Troubleshooting
Busbar does not fit devices.
Ensure the devices are compatible Schneider Electric models (iC60, iID, ISW-NA, iK60, iID K, ISW) and that the busbar has been cut cleanly and to the correct length for the 45mm pitch.
Loose connection.
Re-seat the busbar ensuring it is fully engaged in the device terminals. Check for any debris or damage on the busbar or device connection points.
Overheating at connection point.
Immediately disconnect power. Inspect the busbar and device terminals for damage or excessive resistance. Ensure the busbar is rated for the load and properly seated. If overheating persists, replace the busbar and/or affected devices.
Difficulty in cutting the busbar.
Use a sharp, appropriate cutting tool designed for electrical busbars. Ensure the busbar is properly supported during cutting.
Pros and Cons
Pros
- Highly flexible due to its cutable design.
- Wide compatibility with popular Schneider Electric modular devices.
- Simplifies wiring and reduces installation time compared to individual wire connections.
- Robust construction ensures reliable performance.
- Contributes to a tidier and more organized electrical panel.
Cons
- Requires precise cutting for proper fit, potential for error if not done carefully.
- Limited to 2-pole applications.
- Not suitable for applications exceeding 100A continuous current.
- Compatibility is specific to listed Schneider Electric devices; check before purchase.
- Installation requires basic electrical knowledge and adherence to safety standards.
Setup, Compatibility & Care
Setup:
- Ensure the power supply to the distribution board is completely isolated.
- Identify the devices the busbar will connect (e.g., iC60, iID, ISW-NA, iK60, iID K, ISW).
- Determine the required length of the busbar by measuring the space available and counting the number of devices to be connected (up to 22 devices possible based on 45mm pitch and 57 modular spacings).
- Using appropriate cutting tools, cut the busbar to the desired length. Ensure the cut is clean and square.
- Slide the busbar into the connection slots of the compatible devices, ensuring secure engagement.
- Connect the incoming power supply to the busbar termination.
Compatibility:
This busbar is specifically designed for use with:
- Schneider Electric iC60 series
- Schneider Electric iID series
- Schneider Electric ISW-NA series
- Schneider Electric iK60 series
- Schneider Electric iID K series
- Schneider Electric ISW switch disconnectors
Verify the specific model numbers of your devices to ensure compatibility before installation. The busbar features a 45mm pitch, suitable for devices with standard modular spacings.
Care:
- Keep the busbar clean and free from dust and debris.
- Avoid exposing the busbar to excessive moisture or corrosive environments.
- Periodically inspect connections for tightness and signs of wear. (Power must be disconnected before inspection).
