Space-Efficient Double-Deck Terminal Connections
Double-deck terminal blocks increase wiring density by arranging connections across two levels within a single DIN rail position. This configuration is particularly useful in control cabinets where rail space is limited, allowing panel builders to accommodate additional signal connections without significantly increasing the overall width of the terminal assembly.
The ENTRELEC M4/6.D2 combines this space-saving architecture with established screw-clamp technology and strong electrical performance. Its 4 mm² rated cross-section, 32 A IEC current rating and compact 6 mm width make it a practical solution for high-density industrial control, signal and automation wiring.
Typical Applications
- Industrial electrical control panels.
- High-density signal wiring installations.
- Machine control and automation systems.
- PLC and instrumentation wiring.
- OEM machinery and production equipment.
- Space-constrained DIN rail terminal assemblies.
