Product Information
Full details
This Schneider Electric Acti 9 comb busbar (A9XPH412) is designed for electricians and system integrators requiring a reliable solution for interconnecting multiple devices in phase and neutral circuits. Its key benefit is simplifying complex wiring by providing a single, organized connection point for up to 12 modules. A potential caveat is its fixed 4-pole configuration, which may require cutting for single-phase applications.

Extended Product Information
FAQs
What is the primary purpose of a comb busbar like the A9XPH412?
A comb busbar simplifies electrical panel wiring by providing a single, organized connection point to distribute power (phase and neutral) to multiple modular devices simultaneously, replacing individual wire connections.
Can this busbar be used for single-phase or two-phase circuits?
Yes, although it is a 4-pole busbar, it can be cut to size to accommodate single-phase or two-phase applications by utilizing only the necessary poles and modules.
What is the maximum current this busbar can handle?
The A9XPH412 comb busbar has a rated continuous current of 100A.
What specific Schneider Electric devices are compatible with this busbar?
It is compatible with Schneider Electric Acti 9 series devices such as iC60, iK60, iID, iID K, iSW, and iSW-NA.
How do I ensure a safe installation?
Always de-energize and lock out the power source before installation. Ensure the busbar is securely seated and connections are tight. If unsure, consult a qualified electrician.
What does 'Green Premium' verification mean?
Green Premium is Schneider Electric's label indicating compliance with environmental standards, including RoHS (Restriction of Hazardous Substances) and specific ecotoxicity information.
What is the pitch measurement (18mm) referring to?
The 18mm pitch refers to the standard spacing between the connection points on the busbar and the corresponding terminals on compatible modular devices, ensuring proper alignment and fit.
Troubleshooting
Busbar does not fit into device terminals.
Ensure you are using compatible Schneider Electric Acti 9 devices. Verify that the busbar has not been deformed and that the device terminals are clear of obstructions.
Overheating at connection points.
Check that the busbar is fully seated in all terminals. Ensure the connected devices are rated for the load and that all connections are torqued to the manufacturer's specifications. Inspect for any damage to the busbar or device terminals.
Inconsistent power across connected devices.
Verify that the main power feed to the busbar is stable. Check the integrity of the busbar itself and ensure all connections are secure and making proper contact.
Difficulty cutting the busbar to size.
Use a sharp, high-quality cutting tool designed for metal conductors. Ensure the busbar is securely held while cutting to prevent jagged edges.
Pros and Cons
Pros
- Simplifies complex wiring by consolidating phase and neutral connections.
- High current capacity (100A) suitable for robust installations.
- Compatible with a wide range of Schneider Electric Acti 9 devices.
- Cuttable design allows for flexible installation and custom configurations.
- Enhances safety and organization within electrical panels.
Cons
- Fixed 4-pole design may require modification (cutting) for 1 or 2-pole circuits.
- Requires precise measurement and cutting for non-standard lengths.
- Not suitable for DC applications.
Setup, Compatibility & Care
Setup:
- Ensure the main power supply is de-energized and locked out.
- Determine the required number of modules for your installation. If the full 12 modules are not needed, use a suitable cutting tool (e.g., insulated hacksaw) to cut the busbar to the desired length.
- Align the comb busbar with the connection points on the compatible Schneider Electric devices (iC60, iK60, iID, iID K, iSW, iSW-NA).
- Firmly push the busbar into the designated slots on the devices until securely seated.
- Connect the main power conductors to the appropriate terminals on the first and last devices connected by the busbar.
Compatibility:
This comb busbar is specifically designed for use with Schneider Electric's Acti 9 series devices, including:
- iC60 Miniature Circuit Breakers
- iK60 Miniature Circuit Breakers
- iID Residual Current Devices
- iID K Residual Current Devices
- iSW and iSW-NA Switch Disconnectors
Always verify compatibility with your specific device models before installation.
Care:
- Keep the busbar clean and free from dust and debris. Use a dry or slightly damp cloth for cleaning.
- Avoid using abrasive cleaners or solvents.
- Periodically inspect the connections for tightness and signs of wear or corrosion, especially in harsh environments.
