QIXING QX5691 Interlocked Switched Socket 4 Pin 125A IEC 60309 IP67

Description

A high-current switched socket with a built-in safety interlock.

The QIXING QX5691 is a CEE Form interlocked switched socket rated 4 pin, 125A, 400V three phase, with an IP67 weatherproof rating. It combines a heavy-duty surface-mount socket with an integral isolating switch and a mechanical interlock, so the socket cannot be switched on until a plug is fully inserted, and the plug cannot be removed while the switch is on. This makes connecting and disconnecting safer, since the contacts are never live while a plug is being inserted or withdrawn. The 4 pin configuration carries three phases and earth, with no neutral, suiting heavy three-phase equipment. These are European-standard industrial connectors conforming to EN/IEC 60309-4, used wherever a robust, weatherproof, high-current switched connection point is required.

What an Interlocked Switched Socket Does

An interlocked switched socket combines three functions in one enclosure: an industrial socket, an isolating on/off switch, and a mechanical interlock linking the two. The interlock enforces a safe sequence – the switch can only be turned on once a plug is fully engaged, and the plug can only be withdrawn once the switch is off. This removes the risk of arcing or live contact that can occur when a plug is inserted or pulled under load, which matters all the more at high current. The QX5691 is the 125A four-pole version, used for the largest three-phase equipment, distribution and site power where a local means of isolation is required.

High-Current Three Phase

With four pins carrying three phases and earth, the QX5691 supplies heavy three-phase equipment at 400V and 125A without a neutral. This is among the highest current ratings in the IEC 60309 range, suited to large motors, distribution boards and main site connections. 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 60309-4 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 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 QX5691 used for?
A: It is a heavy-duty surface-mounted industrial socket with an integral switch and mechanical interlock, used for the largest three-phase equipment, distribution and site power where a safe local means of isolation is needed. The QX5691 is the 4 pin 125A version.

Q: How does the mechanical interlock work?
A: The interlock links the switch and the socket so the switch can only be turned on once a plug is fully inserted, and the plug can only be removed once the switch is off. This means the contacts are never live while connecting or disconnecting.

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.
