Busbar in insulated enclosure Legrand 16 mm² BI1 54 modules model 607046

Legrand insulated busbar 16 mm² BI1 for 54-module enclosures is a compact conductor assembly designed for safe power distribution in modular electrical panels. The product integrates a 16 mm² copper busbar inside an insulating enclosure shaped to occupy 54 DIN-module positions, enabling neat routing and connection of circuit breakers and other modular devices. It is intended to simplify wiring in distribution boards by providing a pre-formed, insulated conductor that reduces the need for separate jumper cables and improves overall panel organization.

Advantages

The insulated enclosure provides electrical isolation around the 16 mm² conductor, reducing the risk of accidental contact and short circuits during installation and maintenance. The preconfigured length and modular spacing correspond to 54 DIN-module positions, which speeds up assembly and ensures consistent alignment with modular devices. Using a factory-made busbar lowers installation time and minimizes the number of individual connections, which can improve reliability and reduce wiring errors.

Suitable for

• Power distribution in residential and commercial distribution boards
• Busbar connection between circuit breakers in switchgear and control panels
• Industrial panels with modular DIN-rail devices requiring 54 module spacing
• Retrofit or new installations where compact, insulated conductors are preferred

Key specifications

• Conductor cross-section: 16 mm²
• Rated for modular enclosure occupancy: 54 DIN-module positions
• Insulating enclosure for touch protection and electrical isolation
• Designed for use with modular circuit breakers and DIN-rail mounted devices
• Compact profile to fit standard panel layouts

How to use

Install the insulated busbar into the distribution board so its module spacing aligns with the centerlines of the modular devices. Secure the enclosure according to the panel manufacturer’s instructions and connect outgoing and incoming conductors to the designated busbar terminals or connection points on the modular devices. Ensure all connections are tightened to the torque values recommended for the terminal types in use and verify that the insulating enclosure is intact and properly positioned before energizing the panel.

Usage recommendations

Verify compatibility of terminal widths and device spacing before installation, and always follow applicable local electrical codes and safety standards. Perform insulation and continuity checks after installation and before switching power. For maintenance, de-energize the panel and confirm absence of voltage prior to removing the insulating enclosure or making changes to wiring.
