Terminal block EPM 12-position double-sided 4 mm pitch model E-650-0140

The EPM 12-position double-sided terminal block with 4 mm pitch (model E-650-0140) provides a compact platform for secure electrical connections in control panels, distribution blocks and industrial wiring assemblies. It features two rows of 12 terminals arranged on a 4 mm center-to-center pitch, enabling density where space is limited while maintaining standard spacing for common wiring practices. The block supports screw/clamp style connection suitable for signal and low-voltage power wiring, offering a reliable interface for panel assemblies and terminal strip replacements.

Advantages

The double-sided construction allows connections on both sides of the block, reducing the need for additional terminal strips and simplifying wiring layouts. The 4 mm pitch aligns with widely used wire management standards, facilitating fast installation and compatibility with common ferrules and connectors. Screw/clamp style terminations provide mechanical retention and straightforward reworkability for maintenance or circuit changes.

Suitable for

• Control panels and automation cabinets
• Distribution blocks and junction points
• Signal wiring and low-voltage power circuits
• Terminal strip replacements and compact wiring assemblies

Key specifications

• Number of positions: 12 positions per side, double-sided arrangement
• Pitch: 4 mm center-to-center
• Termination style: screw/clamp type suitable for stranded and solid conductors
• Mounting: designed for compact panel or DIN-rail style integration (panel assemblies)
• Application voltage level: intended for signal and low-voltage wiring

How to use

Mount the terminal block in the designated location within the panel or on the terminal rail according to the enclosure layout. Strip conductor insulation to the recommended length for the screw/clamp terminals and insert each conductor fully before tightening the screw to the manufacturer's recommended torque. For double-sided connections, ensure clear labeling and routing to avoid cross-connections between the two rows. Verify mechanical and electrical continuity after installation and re-check terminal tightness after initial system energization.

Usage recommendations

Use appropriately sized ferrules or insulated end sleeves on stranded conductors to improve contact reliability. Follow standard wiring color codes and label both sides of the double-sided block to maintain clear circuit identification during maintenance and expansions.
