Terminal block Simet LTF 12-4.0 12-way 4 mm² screw-clamp, orange

Simet LTF 12-4.0 is a 12-way screw-clamp terminal block engineered for reliable electrical connections in control panels, junction boxes and industrial installations. The compact orange housing groups twelve individual clamping points, each accepting conductors up to 4 mm², enabling organized termination and distribution of signal and power circuits. The unit is intended for fixed-panel mounting and provides clear separation between channels for straightforward wiring and maintenance.

Advantages

The screw-clamp design offers robust mechanical retention and low contact resistance for conductors up to 4 mm², delivering stable electrical continuity. The compact 12-way layout reduces panel space while maintaining accessible terminal points. The orange insulating body provides visual identification in multi-row assemblies and simplifies circuit tracing. The construction is aimed at long-term service in standard industrial environments.

Suitable for

• Signal and low‑power distribution in control cabinets
• Junction boxes and terminal strips for machinery
• Organized wiring where multiple circuits require individual termination
• Replaceable terminal arrangements in serviceable installations

Key specifications

• Number of poles: 12
• Connection type: screw-clamp terminals
• Maximum conductor cross-section: 4 mm²
• Color: orange
• Mounting style: panel/rail mounting compatible compact unit

How to use

Mount the terminal block in the designated position on the panel or rail, ensuring secure mechanical fixation. Strip conductors to the recommended length for the screw-clamp contacts, insert each conductor into its respective clamping point and tighten the screw to the specified torque for the conductor size. Verify that each connection is firm and that insulation is not pinched. Label or mark circuits as required for future identification.

Usage recommendations

Use properly sized conductors (up to 4 mm²) and the correct screwdriver to avoid over‑ or under‑tightening. Follow local electrical standards and torque values for screw‑clamp terminals. For installations exposed to vibration or thermal cycling, periodically inspect terminal tightness and re‑test continuity as part of routine maintenance.
