Product Information
Full details
The nVent ERIFLEX Distribution Block (MPN: 563990) is designed for electrical contractors and panel builders needing a reliable method to distribute power. Its key benefit is high current capacity (160A) with versatile terminal options, allowing for efficient and safe wiring. A potential caveat is its fixed pole configuration, requiring careful planning for specific system designs.

FAQs
What is the maximum current rating for this distribution block?
The nVent ERIFLEX Distribution Block (563990) has a maximum current rating of 160A.
What sizes of wires can be connected to this block?
The input terminal accepts conductors from 10mm² to 50mm². The output terminals accept 3 conductors from 10mm² to 35mm² and 8 conductors from 2.5mm² to 16mm².
How many poles does this distribution block have?
This distribution block has 4 poles.
Can this block be mounted on a standard DIN rail?
Yes, this distribution block is designed for standard DIN rail mounting, facilitating easy installation in electrical panels.
What type of conductors are recommended for use?
This block is designed for use with copper conductors.
Do I need special tools to install wires?
While standard screwdrivers are used for terminals, a torque wrench is highly recommended to ensure proper tightness, and specialized tools may be needed for crimping or preparing larger gauge conductors.
Is this distribution block suitable for outdoor use?
This block is designed for use within electrical enclosures and panels. Its suitability for outdoor use depends on the enclosure's NEMA/IP rating and environmental conditions.
Troubleshooting
Block feels warm during operation
Check if terminal screws are tightened to the correct torque. Ensure conductors are properly seated and of the correct gauge for the terminal. Verify the total current draw does not exceed the 160A rating.
Wire termination is loose
Ensure the conductor is stripped to the correct length and inserted fully into the terminal. Re-tighten the terminal screw using a torque wrench to the specified value. Check conductor for damage or corrosion.
Difficulty inserting larger gauge wires
Confirm you are using the correct input or output terminal designed for that wire gauge (e.g., 50mm² input). Ensure the conductor end is clean, square, and free of deformation.
Block shows signs of overheating or melting
Immediately de-energize the circuit. Inspect for loose connections, undersized conductors, or sustained current draw exceeding the 160A rating. Replace the damaged block and address the root cause.
Pros and Cons
Pros
- Handles high amperage (160A) safely.
- Offers flexibility with multiple output wire terminal sizes.
- Simplifies complex wiring by consolidating power input.
- Durable construction ensures longevity in demanding environments.
- 4-pole design is space-efficient for panel building.
Cons
- Fixed 4-pole configuration may not suit all system requirements.
- Requires specific tools for proper wire termination.
- Higher upfront cost compared to basic terminal strips.
- Larger conductor sizes for input may need specialized crimping tools.
- Not suitable for low-voltage or signal distribution.
Setup, Compatibility & Care
Setup:
- Ensure the main power source is de-energized.
- Mount the distribution block securely to a DIN rail or back panel using appropriate mounting hardware.
- Strip conductor insulation to the length specified for the terminal size.
- Insert conductors into the appropriate input and output terminals.
- Use a torque wrench to tighten terminal screws to the recommended torque value (refer to nVent ERIFLEX documentation for specific values) to ensure a secure connection and prevent overheating.
Compatibility:
- Compatible with conductors ranging from 2.5mm² to 50mm² (see specific terminal limits).
- Designed for use with copper conductors.
- Suitable for installation in electrical enclosures and panels.
Care:
- Regularly inspect connections for tightness, especially after initial installation and during scheduled maintenance.
- Keep the unit clean and free from dust and debris. Use a dry or slightly damp cloth for cleaning; avoid solvents.
- Ensure ventilation around the block is not obstructed to prevent overheating.
