QIXING QX357 Appliance Inlet 4 Pin 63A IEC 60309 IP67

Description

A fixed inlet for three-phase supply.

The QIXING QX357 is a CEE Form appliance inlet (surface mounted plug) rated 4 pin, 63A, 400V three phase, with an IP67 weatherproof rating. It is a male pin connector in a surface-mount housing that bolts to a wall or equipment face, providing a fixed inlet that a trailing socket or connector plugs onto. This makes it ideal for feeding power into fixed equipment, enclosures and machinery where a permanent, weatherproof connection point is required. These are European-standard industrial connectors conforming to EN/IEC 60309-2.

What an Appliance Inlet Does

An appliance inlet, also called a surface mounted plug, is a male connector built into a surface-mount housing. It bolts to a wall, panel or piece of equipment and presents pins that a trailing socket or connector plugs onto, creating a fixed point at which power is fed into the equipment. The QX357 is the 63A four-pole version, used to bring a three-phase supply into machinery, enclosures and fixed plant.

Three Phase, Weatherproof

With four pins carrying three phases and earth, the QX357 provides a 400V, 63A three-phase inlet without a neutral. Rated IP67, it is protected against dust and the effects of temporary immersion in water, making it suitable for 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 inlet only connects with a matching socket of the correct voltage rating and configuration.

Q: What is the QX357 used for?
A: It is a surface-mounting appliance inlet that bolts to a wall or equipment face, providing a fixed three-phase point at which power is fed into machinery or enclosures via a trailing socket. The QX357 is the 4 pin 63A version.

Q: How does it mount?
A: It bolts to a flat surface through its mounting holes, with the pins facing outward. Conductors are connected internally, and the M40 cable entry can be cut to suit the cable.

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