Bloco de barramento Legrand 04917, 3 polos, 12 TE, 10 mm²

Legrand 04917 is a 3-pole busbar rail designed for modular electrical distribution in control panels and DIN-rail installations. With a width of 12 TE and conductor capacity up to 10 mm², this busbar rail provides a compact, standardized solution for making secure electrical connections between devices and circuit breakers. The product is intended for installations where consistent phase distribution and neat wiring are required.

Advantages

The busbar rail offers a compact footprint compatible with 12 TE mounting space, allowing organized routing of three phases in a single rail. Its design supports conductors up to 10 mm², enabling reliable current carrying capacity for a range of low- and medium-power circuits. The standardized mounting and clear phase separation simplify installation and maintenance while reducing wiring errors in distribution panels.

Key specifications

How to use

Install the busbar rail onto the DIN-rail or within the switchboard in the designated 12 TE space, ensuring proper mechanical engagement and alignment. Route the phase conductors to the corresponding poles and secure them according to the installation practice for the mounted protective devices. Verify that conductor cross-sections do not exceed 10 mm² and that connections are tightened to recommended torque values of the connected devices. After installation, perform continuity and insulation checks and confirm proper phase sequencing before energizing the system.

Recommendations

Use the busbar rail in compliance with local electrical codes and the technical instructions of connected equipment. Ensure compatible circuit-breakers and terminal accessories are selected for 12 TE layouts and that conductor sizes and tightening torques match the busbar and device specifications. Periodically inspect electrical connections for corrosion, tightness, and proper insulation.
