Barra collettrice per interruttori automatici Rittal SV 3418.040, 400 V, 63 A, 41×251 mm

Rittal SV 3418.040 is a circuit breaker busbar designed for three-pole installations in electrical enclosures and switchgear. Rated for 400 V and 63 A with a compact cross-section of 41×251 mm, it supports reliable power distribution and secure connection of protective devices. The product is intended for systems with a 60 mm bar centre distance and is suitable for industrial and commercial panel installations where a space-efficient busbar for circuit breakers is required.

Advantages

The busbar offers a combination of compact dimensions and rated current capacity that allows efficient use of enclosure space while maintaining the required electrical performance. Its three-pole design and compatibility with a 60 mm bar centre distance simplify integration with standard circuit breakers and mounting systems. Constructed for routine panel and switchgear applications, it supports stable connections and consistent current carrying capability under typical operating conditions.

Key specifications

How to use

Install the busbar into the enclosure following the enclosure manufacturer's instructions and applicable electrical installation standards. Position the busbar to align with the 60 mm centre distance for circuit breaker connections, secure it mechanically using the recommended fasteners, and make electrical connections according to torque specifications for the chosen breakers and conductors. Verify correct phase orientation and insulation clearances before energizing the system. Perform routine inspection after installation to confirm secure mechanical fixing and proper electrical contact.

Recommendations

Use the busbar only with compatible circuit breakers and mounting hardware that match the 60 mm bar centre distance and the rated electrical parameters. Ensure all work is performed by qualified personnel and comply with local regulations and safety standards. Regularly inspect connections for corrosion, looseness, or wear and verify that the operating current does not exceed the rated 63 A.
