When it may not be suitable

This busbar is specifically designed for 1P+N configurations and slim circuit breakers. It is not suitable for standard-width circuit breakers or multi-phase systems that require different pin arrangements or higher cross-sections. Attempting to use this component with incompatible hardware may result in poor electrical contact or safety hazards.

Key specifications

• Cross-section: 10 mm2
• Configuration: 1-pole + Neutral (1P+N)
• Capacity: 12 modules
• Type: Pin-type busbar
• Safety: Fully insulated with touch protection

How to use

To install the busbar, ensure that the power supply to the distribution board is completely disconnected. Align the pins of the busbar with the terminals of your compatible slim circuit breakers. Insert the pins firmly into the terminal slots and tighten the terminal screws according to the manufacturer's torque specifications. Ensure that the busbar is seated correctly and that no exposed metal parts are accessible. Once installed, verify the connections before restoring power to the system.

What to consider before purchase

• Verify compatibility with your specific circuit breaker series
• Ensure the 12-module length fits your distribution board layout
• Check that the 10mm2 cross-section meets your circuit's current requirements
• Confirm the 1P+N configuration matches your electrical system design

Usage recommendations

Always ensure that the installation is performed by a qualified electrician in accordance with local electrical codes and safety regulations. Regularly inspect the connections for any signs of wear or thermal stress to maintain long-term system reliability.
