## Long description

Electro base terminal block E-2273-203 is a 3‑pole connector designed to accept conductors with cross-sections from 0.5 to 2.5 mm². Supplied as a pack of 100, this compact terminal block is intended for secure, low-profile electrical connections in control panels, distribution boards and general wiring runs. It is suitable for joining, branching or terminating single-core and stranded conductors in industrial and building electrical installations where space efficiency and reliable contact are important.
Advantages
The terminal block provides stable electrical contact and mechanical retention for conductors within the specified cross-section range. Its three-pole configuration allows neat arrangement of multiple conductors in a compact footprint. Supplied in a pack of 100, it supports bulk installation work and reduces handling time. The design minimizes contact resistance and facilitates secure screw or clamp fastening accessible from the exterior, ensuring repeatable and maintainable terminations.
Suitable for
 Internal wiring of control panels and switchgear
 Distribution boards and terminal strips
 Branching and terminating single-core or stranded conductors
 Industrial machinery wiring and building electrical installations
Key specifications
 Poles: 3
 Conductor cross-section range: 0.5–2.5 mm²
 Pack quantity: 100 pieces
 Mounting style: panel or DIN rail compatible (check mounting variant)
 Connection type: screw/clamp style suitable for single-core and stranded conductors
 Typical application temperature range suitable for electrical enclosures
How to use
Prepare conductor ends by stripping insulation to the recommended length for the chosen connection method. Insert conductors into the terminal holes and fasten using the screw or clamp mechanism until a firm mechanical and electrical connection is achieved; avoid over-tightening. Assemble the terminal blocks into the panel or mounting rail according to the installation layout, observing appropriate clearances and torque values for consistent contact pressure. Verify continuity and proper insulation after installation and before energizing the circuit.
Usage recommendations
Use the terminal block within the specified conductor cross-section limits and follow applicable wiring regulations. For stranded conductors, consider using ferrules to improve mechanical reliability. Apply recommended torque values for screws to avoid damage and ensure consistent contact resistance. Store the pack in a dry environment to prevent corrosion prior to installation.
