Description

The Neutrik NAC3FXXB-W-S is a 20A PowerCon power-out connector with a grey locking housing and screw terminal assembly for cables between 6-12mm diameter. The connector uses a keyed twist-lock mechanism that prevents accidental disconnection during use and cannot be intermated with power-in (blue) versions, ensuring correct polarity in daisy-chain power distribution.

Designed for professional audio, lighting and video installations where appliance couplers would be inadequate, the NAC3FXXB provides circuit-breaking capability when mated with PowerCon XX Series panel receptacles. The three-conductor single-phase connector handles live, neutral and earth connections through screw terminals rated to 250V AC and 20A maximum load. Typical applications include powered speaker systems, stage lighting rigs, and rack-mounted AV equipment where robust mains distribution is needed.

The grey housing indicates power-out configuration, differentiating it from power-in (blue) connectors through both colour coding and physical keying. The strain relief locks mechanically with the internal insert and aligns automatically with the housing during assembly, reducing installation time and eliminating the risk of misalignment. The IP20 rating provides protection against solid objects larger than 12.5mm but not against water ingress, making this connector suitable for indoor installation only.

Neutrik rates the NAC3FXXB for 5,000 typical mating cycles with a contact resistance below 2 milliohms and an operating temperature range of -33°C to +80°C. The connector body is built from impact-resistant thermoplastic with nickel-plated brass contacts.

Frequently Asked

What's the difference between power-in and power-out PowerCon connectors?

Power-out connectors (grey, model NAC3FXXB) are keyed differently from power-in connectors (blue, model NAC3FXA) and cannot be physically intermated with each other. This prevents reverse polarity when daisy-chaining mains power through multiple devices. Always use power-out on the cable that feeds the next device in the chain.

What cable diameter does this connector accept?

The NAC3FXXB-W-S accepts cable outer diameters from 6mm to 12mm. The strain relief clamps onto the cable jacket and locks mechanically with the internal insert, so choosing cable within this range ensures proper strain relief and IP rating.

Is this connector waterproof?

No. The IP20 rating provides protection against solid objects larger than 12.5mm but offers no protection against water ingress. This connector is designed for indoor installation only and should not be used in outdoor or wet environments.

What current and voltage rating does it carry?

The NAC3FXXB is rated to 250V AC and 20A maximum load. This gives a maximum power handling capacity of 5,000W on a single-phase circuit, which covers most professional audio and lighting equipment.
