FAQs
What is the maximum current this terminal can handle?
The Legrand 400411 has a nominal current rating of 160 A.
What wire sizes can be used with this terminal?
This terminal supports wire sizes ranging from 35 mm² to 70 mm².
How is this terminal mounted?
It is designed for standard DIN rail mounting.
Is this terminal suitable for outdoor use?
This terminal is designed for use within electrical enclosures and distribution boards. Its suitability for outdoor applications depends on the environmental protection ratings of the enclosure it is installed within.
What does '4-pole' mean in this context?
A 4-pole terminal allows for the connection of up to four separate conductors.
What type of connection does it use?
It uses screw clamp connections for securing the wires.
Troubleshooting
Terminal overheating
Check that all screws are fully tightened and that the connected wire gauge is within the specified range (35-70 mm²). Ensure the current load does not exceed the 160 A rating. Inspect wires for damage.
Wire will not insert into terminal
Verify that the wire gauge is within the supported range (35-70 mm²). Ensure the wire end is cleanly cut and not frayed. Loosen the screw clamp fully.
Terminal not securing to DIN rail
Ensure you are using a standard 35mm DIN rail. Check that the rail is properly mounted and not warped. Re-seat the terminal, ensuring it clicks or latches into place.
Pros and Cons
Pros
- Robust construction for industrial and commercial use.
- Secure screw clamp connections prevent wire slippage.
- Easy DIN rail mounting simplifies installation.
- High current rating supports significant power loads.
- Designed for main cable applications, ensuring reliability.
Cons
- Limited to 4 poles, which may not be sufficient for complex circuits.
- Requires specific wire sizes (35-70 mm²), limiting flexibility.
- Dimensions may require careful planning in confined spaces.
- Primarily for main cable connections, not general-purpose wiring.
- Requires DIN rail for mounting, necessitating compatible infrastructure.
Setup, Compatibility & Care
Setup: This terminal is designed for DIN rail mounting. Ensure the DIN rail is securely installed in your electrical enclosure. Slide the terminal onto the rail, ensuring it latches firmly in place. Connect the main cables by stripping the appropriate amount of insulation from the wires (refer to electrical codes for precise stripping lengths) and inserting them into the designated screw clamp terminals. Tighten the screws securely using an appropriate screwdriver. Always ensure power is disconnected before installation.
Compatibility: The Legrand 400411 is compatible with standard 35mm DIN rails. It is designed for use with copper conductors in the range of 35 mm² to 70 mm².
Care: This is a maintenance-free component under normal operating conditions. Periodically, during scheduled electrical inspections, visually check for any signs of overheating or loose connections. Ensure the enclosure is clean and free from dust and moisture that could affect electrical components.
