Rack accessory Rittal 9342.250 — busbar connector, 35–120 mm², max 250 A, 690 V, 90×210 mm, ABS/PA, grey

Rittal 9342.250 is a busbar connector intended for installation in electrical enclosures and industrial racks. The compact module accepts round conductors with cross-sections from 35 to 120 mm² and is rated for a maximum current of 250 A at up to 690 V. The housing is made of ABS and polyamide in grey and the unit is delivered as a single piece ready for integration into switchgear and distribution systems.

Advantages

The connector offers a clear mechanical design that enables reliable clamping of round conductors and a defined clamping area of 18.5 × 15.5 mm. The product supports three-pole connections with cable outlets at top and bottom, allowing flexible routing in compact enclosures. Its construction from ABS and PA provides electrical insulation and mechanical stability suitable for industrial environments. The unit is CE certified and designed for straightforward integration into existing busbar and distribution systems.

Key specifications

How to use

Mount the busbar connector into the appropriate slot or mounting point in the enclosure according to the cabinet layout. Prepare round conductors by stripping insulation to the required length, then insert each conductor into the corresponding clamping point and tighten the terminal screws to the torque values recommended by the overall system documentation. Ensure the connector orientation matches the planned cable routing to use the top or bottom cable outlet as needed. After installation, verify electrical continuity and insulation resistance before applying operational voltage.

Recommendations

Use conductors within the specified 35–120 mm² range and adhere to the system’s torque and installation instructions. For safe operation, confirm coordination with upstream protection devices rated for 250 A or appropriate for the system design. Keep the connector and its surroundings free of conductive debris and perform periodic visual and torque checks as part of routine maintenance.
