## Summary description

Simet Simblock STB 185 is a threaded rail terminal connector for Al/Cu conductors, model 81201003 in blue. Designed to join aluminium and copper cables securely on distribution rails, it provides a reliable mechanical and electrical connection for power distribution and grounding applications in electrical panels and switchgear.

## Long description

Simet Simblock STB 185 is a threaded rail terminal connector designed for reliable mechanical and electrical joining of aluminium and copper conductors on distribution rails. Supplied in blue, this connector is intended for use in electrical panels and switchgear where secure power distribution and grounding connections are required. The product supports mixed-metal termination and is built to maintain contact integrity under typical installation torque and environmental conditions found in commercial and industrial installations.
Advantages
The threaded design ensures a secure clamp on both aluminium and copper conductors and reduces the risk of loosening due to vibration. Construction materials and geometry are chosen to provide consistent contact pressure and low contact resistance. The blue insulation or marking provides quick visual identification on distribution rails and inside switchgear cabinets. Compatibility with standard rail mounting methods simplifies installation and maintenance.
Suitable for
 Joining aluminium and copper conductors on distribution rails
 Power distribution terminals in electrical panels and switchgear
 Grounding and earthing connections where mixed-metal conductors are present
 Commercial and industrial electrical installations requiring threaded rail connectors
When it may not be suitable
This connector is intended for use on distribution rails and may not be appropriate for free-hanging or unsupported conductor terminations where a dedicated lug or crimped connector is required. It is also not intended as a direct substitute for connectors specified for specialized environments such as high-corrosion marine applications unless additional protective measures are applied.
Key specifications
 Conductor compatibility: aluminium and copper
 Connection type: threaded rail terminal connector
 Color: blue (insulation/identification)
 Application: distribution rails in panels and switchgear; power distribution and grounding
 Mounting: rail-mounted (compatible with standard distribution rails)
How to use
Ensure the distribution rail is de-energized before starting installation. Prepare conductor ends according to local electrical codes—clean and strip to the appropriate length. Position the conductor into the connector and tighten the threaded clamp to the manufacturer-recommended torque using an appropriate torque wrench or driver; this ensures correct contact pressure and minimizes contact resistance. After tightening, perform a visual inspection and, if required by installation standards, measure continuity or contact resistance to confirm a proper connection.
What to consider before purchase
 Verify conductor cross-sections and compatibility with aluminium and copper cables used in your installation
 Confirm compatibility with the specific type and size of distribution rail in your panel or switchgear
 Check required tightening torque and whether a calibrated torque tool is needed for installation
 Assess environmental conditions (humidity, corrosive atmosphere) and whether additional protection is necessary
Usage recommendations
Use a calibrated torque tool and follow local electrical codes when installing the Simet Simblock STB 185. For long-term reliability, periodically inspect connections in environments subject to vibration or temperature cycling and re-torque if inspection guidelines indicate.
