Product Information
Full details
This nVent ERIFLEX 4-way distribution block is designed for electricians and panel builders needing a reliable and efficient method for power distribution. Its key benefit is simplifying complex wiring by consolidating multiple connections into a single, robust unit, though its fixed configuration means it may not suit every unique circuit layout. This terminal block features screw clamp termination, a thermoplastic housing, and accommodates conductor sizes from 10 to 35mm² with a maximum current rating of 125A at 690V.

Extended Product Information
FAQs
What is the maximum number of connections this block supports?
This is a 4-way distribution block, meaning it supports one incoming connection and four outgoing connections.
What types of conductors can be used?
It is designed for single-core or fine-stranded copper conductors within the 10mm² to 35mm² cross-section range.
What is the maximum voltage and current rating?
The maximum operating voltage is 690V, and the maximum continuous current is 125A.
What is the housing material?
The housing is made of durable thermoplastic, providing electrical insulation and environmental protection.
Can this block be used outdoors?
While the thermoplastic housing offers some protection, it is primarily designed for use within electrical enclosures or panels. Outdoor use would depend on the environmental protection provided by the enclosure.
How do I ensure a secure connection with the screw clamps?
Insert the properly stripped conductor into the terminal opening and tighten the screw clamp firmly. A torque screwdriver can be used to achieve the recommended torque, if specified by the installation standard.
Troubleshooting
Connection is loose or intermittent
Ensure the conductor is fully inserted and the screw clamp is tightened firmly. Check that the conductor size is within the 10-35mm² range and that the conductor is not damaged.
Block overheating
Verify the current draw does not exceed the 125A rating. Check all connections for proper tightness. Ensure adequate ventilation around the distribution block.
Difficulty inserting conductor
Confirm the conductor is stripped to the correct length and that the conductor is not bent or damaged. Ensure no foreign debris is present in the terminal opening.
Pros and Cons
Pros
- Simplifies complex wiring by consolidating multiple connections.
- Offers secure and reliable connections via screw clamp terminals.
- Accommodates a broad range of conductor sizes for versatile use.
- High current and voltage ratings allow for use in robust power distribution systems.
- Durable construction ensures longevity and safety.
Cons
- Fixed 4-way configuration may not suit all custom wiring needs.
- Requires specific conductor sizes within the supported range.
- Not suitable for applications exceeding its voltage or current ratings.
Setup, Compatibility & Care
Setup: Ensure the power source is de-energized before installation. Strip the conductor ends to the appropriate length as recommended for screw clamp terminals. Insert conductors into the designated slots and tighten the screw clamps firmly to secure the connection. Verify all connections are snug before re-energizing the circuit.
Compatibility: This block is compatible with single-core or fine-stranded copper conductors within the 10mm² to 35mm² cross-section range. It is designed for use in 690V systems. Ensure the ambient temperature is within the operational limits of the thermoplastic housing.
Care: Periodically inspect connections for tightness, especially in environments with significant vibration. Clean the exterior of the block with a dry or slightly damp cloth to remove dust and debris. Avoid using abrasive cleaners or solvents that could damage the housing. Ensure ventilation around the block is not obstructed.
