Rittal SV 9340.730 OM-Adapter 40A 3-pole for TS55D distribution rails

The Rittal SV 9340.730 OM-Adapter is a 3-pole distribution adapter designed for use on TS55D equipment rails. Rated for 40 A and suitable for AWG8 conductors, this single-unit adapter provides a compact, rail-mounted solution for distributing power within control cabinets and switchgear. Its form factor and mounting compatibility allow integration into standard TS55D layouts, enabling organized routing and secure connections for three-phase or multi-pole installations.

Advantages

The adapter offers a clear technical specification with a 40 A current rating and three-pole configuration, reducing uncertainty during component selection. Its compatibility with AWG8 conductors simplifies cabling choices, and the rail-mount design supports quick installation on TS55D distribution rails. Supplied as a single unit, the adapter facilitates targeted use where only one distribution point is required, and its compact dimensions help conserve space inside enclosures.

Suitable for (tasks / use cases)

• Power distribution on TS55D equipment rails in control cabinets
• Three-pole connections for small to medium electrical loads up to 40 A
• Installations using AWG8 conductors where secure rail-mounted adapters are needed
• Retrofit or expansion of existing switchgear layouts that use TS55D rails

When it may not be suitable

This OM-adapter is not intended for applications requiring higher current than 40 A or for single-pole distribution needs. It is specifically designed for TS55D rail systems; installations using different rail standards or bespoke mounting arrangements may require alternative adapters or mounting hardware. For conductors larger than AWG8 or systems with different conductor types, verify compatibility before selection.

Key specifications

• Number of poles: 3
• Rated current: 40 A
• Conductor compatibility: AWG8
• Mounting type: TS55D equipment rail
• Units supplied: single adapter

How to use

Mount the OM-adapter onto the TS55D distribution rail at the chosen location, ensuring the adapter snaps or fastens securely according to the rail’s mounting profile. Route AWG8 conductors to the adapter terminals, observing correct phase sequencing and secure conductor termination practices. Tighten terminal connections to the torque values recommended by Rittal or by your installation standards, and verify insulation clearances and protective devices are in place before energizing the circuit.

What to consider before purchase

• Confirm the distribution rail is the TS55D type and that physical mounting dimensions match available space
• Ensure the required current does not exceed 40 A for the intended circuit
• Verify conductor size and type; the adapter is specified for AWG8 compatibility
• Check whether single-unit supply meets the number of distribution points needed for the installation

Usage recommendations

Use this OM-adapter for organized three-pole distribution inside TS55D-equipped control cabinets and switchgear. Ensure proper terminal tightening, phase identification, and protective device coordination. For installations with different rail types, higher currents, or larger conductors, select components rated for those specific conditions.
