Rittal OM-Adapter with Connection Cables 690V, polyamide light gray (RAL 7035) for busbar system, model 9340.790

Rittal OM-Adapter 9340.790 is an OM-series adapter with integrated connection cables rated for up to 690 V, designed for use with busbar and collector systems in electrical distribution and switchgear cabinets. The adapter housing is made of polyamide in light gray (RAL 7035) and provides a compatible mechanical interface for OM mounting systems while enabling safe conductive connections between busbar segments and downstream components.

Advantages

The OM-adapter combines a compact polyamide housing with factory-installed connection cables, simplifying installation and reducing the need for additional wiring materials. Its construction supports installation in standard OM busbar arrangements and contributes to reliable electrical connections under voltages up to 690 V. The neutral color and standard OM form factor allow straightforward integration into cabinet interiors without affecting layout or clearance requirements.

Key specifications

How to use

Install the OM-adapter into the corresponding OM busbar slot or mounting position according to the cabinet layout and local wiring regulations. Ensure supply power is isolated before making any connections. Position the adapter so that the polyamide housing aligns with adjacent busbar elements and secure it per the OM mounting procedure. Connect the factory-fitted cables to the intended terminals or load circuits, observing correct phase and polarity assignments and using appropriate torque values for terminal connections.

Recommendations

Verify compatibility with your existing OM busbar system and ensure the adapter's voltage rating matches system requirements. Follow local electrical codes and perform insulation and continuity checks after installation. Use personal protective equipment and de-energize circuits during fitting and maintenance.
