Application Fields
The M4/6N terminal block is a versatile solution utilized across nearly all industrial sectors, including machine building, HVAC control, and water treatment facilities. Its blue color serves as a standard industry indicator for neutral wiring, helping technicians maintain clear and safe wiring logic. It is ideal for mounting in junction boxes, control cabinets, and distribution boards where organized power and signal routing are required.
Product Instructions
To install, snap the M4/6N module onto a compatible DIN rail. Strip the insulation of the conductor to approximately 9.5 mm and insert it into the screw clamp opening. Use a standard flat-head screwdriver to tighten the screw to the recommended torque (0.5 – 0.8 Nm) to ensure a secure connection. For a complete installation, it is recommended to use end stops at each end of the terminal row and an end section (FEM6) to close the open side of the last terminal block.
Common Questions and Answers
Q: Can I use this terminal block for ground connections? A: While it is physically possible to pass current through it, industry standards require green/yellow terminal blocks (like the M4/6.P) for dedicated earth grounding. The blue M4/6N is specifically intended for neutral conductors.
Q: What is the maximum wire size this terminal can accommodate? A: The M4/6N is rated for a 4 mm² cross-section, but it can typically accommodate solid wires up to 6 mm² or stranded wires with ferrules up to 4 mm².
Q: Does this terminal block require special tools for DIN rail mounting? A: No, the M4/6N features a universal foot design that allows it to be snapped onto standard 35mm DIN rails (top-hat) or G32 rails without the need for additional tools.
