QIXING QX550 CEE Form 5 Pin 16A Extension Socket IEC 60309 IP67

Description

A weatherproof three-phase in-line socket with neutral.

The QIXING QX550 is a CEE Form extension socket rated 5 pin, 16A, 400V three phase, with an IP67 weatherproof rating. It is the female in-line connector – fitted to the end of a flexible lead, it receives a matching plug (such as the QX288) to extend a power run. The 5 pin configuration carries three phases, neutral and earth, suiting three-phase equipment that also requires a neutral. These are European-standard industrial connectors conforming to EN/IEC 60309-2, used wherever a robust, weatherproof connection is required. The 6h clock position keys the connector to its voltage band, helping prevent connection to an incompatible supply.

What an Extension Socket Does

An extension socket is the female in-line connector fitted to the end of a flexible lead. It receives a matching plug to extend a power run, and is the trailing partner to the plugs and inlets in the range. The QX550 is the entry 16A three-phase version with a neutral, used to build light-duty three-phase extension leads and power tails. It mates with a matching 5 pin 16A plug such as the QX288.

Three Phase with Neutral

With five pins carrying three phases, neutral and earth, the QX550 supplies three-phase equipment at 400V and 16A where a neutral is also required. Rated IP67, it is protected against dust and the effects of temporary immersion in water, suiting outdoor, wash-down and demanding industrial locations. As an IEC 60309-2 connector it follows the international pin-and-sleeve standard, so it mates reliably with other IEC 60309 equipment of the same rating and configuration.

Keyed for Safety

The 6h clock position refers to the keyed position of the earth contact under IEC 60309, which corresponds to the connector’s voltage band. This keying helps ensure the socket only connects with a matching plug of the correct voltage rating and configuration.

Q: What is the QX550 used for?
A: It is the female in-line connector fitted to the end of a flexible lead. It receives a matching plug (such as the QX288) to extend a three-phase power run. The QX550 is the 5 pin 16A version, with a neutral.

Q: What is the difference between the 5 pin QX550 and the 4 pin QX544?
A: The QX550 has 5 pins (three phases, neutral and earth), while the QX544 has 4 pins (three phases and earth, no neutral). Both are 16A 400V extension sockets.

Q: What does IP67 mean for this socket?
A: IP67 means it is fully protected against dust and can withstand temporary immersion in water, suiting outdoor and wash-down environments.
