QIXING QX2175 CEE Form 4 Pin 32A Reefer Plug 3H IEC 60309 IP67

Description

A keyed plug for refrigerated containers.

The QIXING QX2175 is a CEE Form Reefer plug rated 4 pin, 32A, 400V three phase, with an IP67 weatherproof rating and a 3H clock position. It is a straight IEC 60309-2 plug – the male connector fitted to the end of a flexible lead, which plugs into a matching Reefer socket to draw power. “Reefer” refers to refrigerated shipping containers, and these connectors supply power to 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 lead from being connected to an incompatible supply. These are European-standard industrial connectors conforming to EN/IEC 60309-2.

What a Reefer Plug Is For

A Reefer plug is the male connector fitted to the end of a flexible lead used to power refrigerated shipping containers. It plugs into a matching Reefer socket on the container or on a power outlet. The QX2175 is the straight version, with the cable entering in line with the body. It is used in ports, on ships, at container depots and in logistics and transport environments wherever refrigerated containers need a power connection.

Why the 3H Clock Position Matters

Under IEC 60309, the clock position sets the keyed orientation of the earth contact, 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 lead cannot be plugged into a standard 400V supply, and vice versa. This separation helps prevent connection to an incompatible system. The QX2175 is a 3H connector and mates with other 3H Reefer equipment of the same rating and configuration.

Weatherproof for Demanding Environments

Rated IP67, the QX2175 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 QX2175 plug used for?
A: It is a Reefer plug, the male connector fitted to the end of a flexible lead used to power refrigerated shipping containers. It plugs into a matching 3H Reefer socket.

Q: What is the difference between a 3H Reefer plug and a standard 6H plug?
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 lead being connected to an incompatible supply.

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