QIXING QX2177 CEE Form 4 Pin 32A Reefer Extension Socket 3H IP67

Description

The in-line socket for Reefer leads.

The QIXING QX2177 is a CEE Form Reefer extension socket rated 4 pin, 32A, 400V three phase, with an IP67 weatherproof rating and a 3H clock position. It is the female in-line connector – fitted to the end of a flexible lead, it receives a matching Reefer plug (such as the QX2175) to carry power along an extension run. “Reefer” refers to refrigerated shipping containers, and these connectors form the power leads that supply the container’s refrigeration unit. The defining feature is the 3H clock position, a keyed arrangement that differs from the standard 6H used on general three-phase equipment, deliberately preventing a Reefer connection being made to an incompatible supply. These are European-standard industrial connectors conforming to EN/IEC 60309-2. Brand supplied based on availability.

What a Reefer Extension Socket Is For

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 partner to the plugs and inlets in the range. The QX2177 is the Reefer version, used to build the power leads that supply refrigerated shipping containers in ports, on ships, at container depots and across logistics and transport sites. It mates with a 3H Reefer plug such as the QX2175.

Why the 3H Clock Position Matters

Under IEC 60309, the clock position sets the keyed orientation of the contacts, which determines what a connector will mate with. Standard three-phase 400V equipment uses the 6H position. Reefer equipment uses 3H, a deliberately different keying so that a Reefer connection cannot be made to a standard 400V supply, and vice versa. This separation helps prevent connection to an incompatible system. The QX2177 is a 3H connector and mates with other 3H Reefer equipment of the same rating and configuration.

Weatherproof for Demanding Environments

Rated IP67, the QX2177 is protected against dust and the effects of temporary immersion in water, suiting the outdoor, wash-down and marine environments where refrigerated containers operate. As an IEC 60309-2 connector it follows the international pin-and-sleeve standard.

Q: What is the QX2177 used for?
A: It is a Reefer extension socket, the female in-line connector fitted to the end of a flexible lead. It receives a matching 3H Reefer plug (such as the QX2175) to carry power to refrigerated shipping containers.

Q: What is the difference between a 3H Reefer connector and a standard 6H connector?
A: The clock position is a different keyed orientation. Reefer equipment uses 3H and standard three-phase equipment uses 6H, so the two will not mate with each other. This prevents a Reefer connection being made to an incompatible supply.

Q: Does the QX2177 match the QX2175 plug?
A: Yes. The QX2177 is the female extension socket and the QX2175 is the male plug. Both are 4 pin 32A 400V 3H Reefer connectors and are designed to mate together.
