Terminal block MOREK MAA2050B10 AL/CU threaded rail connector 1.5–50 mm² TS35 1‑pole 4‑hole blue

MOREK MAA2050B10 is a single‑pole DIN‑rail terminal block designed for secure, threaded connections of aluminium and copper conductors. Intended for mounting on a standard TS35 rail, this terminal accepts conductor cross‑sections from 1.5 to 50 mm² and provides four connection holes within a compact blue housing. The component is engineered for use in electrical distribution, panel wiring and junction points where reliable mechanical and electrical continuity is required.

Advantages

The terminal block combines a wide conductor range with a threaded connection method that ensures strong clamping force and low contact resistance for both AL and CU conductors. The four-hole arrangement allows multiple conductors or jumper links to be connected in a single pole, reducing the need for additional terminals and saving panel space. Its TS35 rail compatibility simplifies assembly and integration into standard industrial and commercial distribution boards.

Suitable for

• Electrical distribution and branch circuits in industrial control panels
• Panel wiring and junctions requiring mixed aluminium and copper conductors
• Applications where multiple conductors must be combined at one pole
• DIN‑rail mounted terminal assemblies in commercial installations

Key specifications

• Pole count: 1 pole
• Conductor compatibility: aluminium (AL) and copper (CU)
• Conductor cross‑section range: 1.5–50 mm²
• Connection type: threaded (screw) clamping
• Number of connection holes per pole: 4
• Mounting: TS35 DIN rail
• Housing colour: blue

How to use

Mount the terminal block onto a TS35 DIN rail by snapping it into place or sliding it along the rail according to panel layout. Strip conductors to the recommended length for the terminal type, insert the AL or CU conductor into one of the connection holes and tighten the screw to the torque value specified by the installation standards for threaded terminal connections. When connecting multiple conductors, ensure each conductor is fully inserted and the screws are tightened evenly to maintain consistent contact pressure and avoid damaging conductors. Follow all applicable electrical codes and safety practices during installation.

Usage recommendations

Use correct conductor preparation and apply recommended torque values to threaded connections to ensure low contact resistance and long‑term reliability. When joining aluminium and copper conductors, use anti‑oxidation compound where appropriate and verify compatibility with local electrical regulations.
