Product Information
Full details
This guide is for professionals needing a secure and reliable AC power connection for equipment, offering a key benefit of a locking mechanism to prevent accidental disconnection. A caveat is its specific use for power-out applications, requiring proper pairing with a power-in connector. The Neutrik NAC3FXXA-W-L is a single-phase, three-conductor locking power connector designed for demanding environments, featuring easy assembly, a twist-lock system, and screw terminals for secure cable termination. It is keyed and color-coded for distinct power-in and power-out identification.

FAQs
What is the difference between the grey and blue Powercon connectors?
The grey connector (like the NAC3FXXA-W-L) is designated for power-out, while the blue connector is for power-in. This color-coding and mechanical keying prevent incorrect connections and ensure safety.
Can I use this connector in outdoor or wet conditions?
No, the NAC3FXXA-W-L has an IP20 rating, meaning it offers protection against solid objects greater than 12.5mm but no protection against water. It should only be used in dry environments or with appropriate weather protection.
What is the maximum number of mating cycles for this connector?
The Neutrik Powercon connectors are typically rated for approximately 5000 mating cycles, indicating a long service life under normal usage conditions.
What cable diameters can this connector accommodate?
This model is designed to accommodate cable diameters ranging from 6mm to 12mm and also 10mm to 16mm, depending on the specific strain relief configuration used during assembly.
Does this connector have circuit breaking capability?
Yes, the NAC3FXXA-W-L is a single-phase connector with integrated circuit breaking capability, providing an added layer of safety.
How do I terminate the wires to the screw terminals?
Strip the wire insulation to the length specified by the terminal design, ensuring no stray strands. Insert the conductor into the terminal and tighten the screw firmly. For stranded wires, using ferrules is recommended for a more secure connection.
What is the temperature range for operation?
The connector can reliably operate within a temperature range of -33 °C to +80 °C.
Troubleshooting
Connector will not lock into the mating connector.
Ensure you are attempting to mate a power-out (grey) connector with a power-in (blue) connector. Check for obstructions in the locking mechanism or on the mating connector.
Loose connection or intermittent power.
Verify that the wires are securely fastened in the screw terminals. Check that the cable is properly seated and the strain relief is engaged. Ensure the cable diameter is within the specified range.
Difficulty assembling the connector.
Ensure the cable outer sheath is correctly positioned for the strain relief. Confirm that the wires are neatly tucked into their respective terminal openings before closing the housing.
Connector appears damaged.
Inspect the housing, locking ears, and internal contacts for any visible cracks, breaks, or corrosion. If damage is found, replace the connector.
Pros and Cons
Pros
- Secure locking mechanism prevents accidental disconnections.
- Clear color-coding and keying for safe power-in/power-out identification.
- Durable construction suitable for professional, high-use environments.
- Easy and quick assembly process saves installation time.
- Reliable screw terminals ensure a solid electrical connection.
Cons
- Specific use as a power-out connector requires a corresponding power-in connector.
- IP20 rating means it's not suitable for wet or dusty environments without additional protection.
- Requires proper cable stripping and termination for secure connection.
Setup, Compatibility & Care
Setup:
- Select the appropriate cable diameter (6-12mm or 10-16mm).
- Strip the cable to the appropriate length according to the terminal design.
- Connect the wires to the corresponding screw terminals within the connector insert.
- Mechanically secure the cable's strain relief to the connector body.
- Assemble the connector housing, ensuring the insert aligns correctly.
- Lock the connector by inserting it into a compatible power-in connector and twisting until it latches.
Compatibility:
- This is a power-out connector (grey). It is designed to mate with Neutrik Powercon power-in connectors (blue, typically NAC3FXXA-W-B). Do not attempt to mate with other connector types.
- Suitable for single-phase, 3-conductor AC power applications.
Care:
- Keep the connector contacts clean and free from debris. Use a dry, lint-free cloth for cleaning.
- Inspect regularly for any signs of damage to the housing, locking mechanism, or contacts.
- Avoid exposure to excessive moisture or harsh chemicals.
- Store in a dry environment when not in use.
