EX plug-in devices, explosion-proof, current-carrying part - socket - 400V, 16A, 4P IP66/67 2514013

Safe Power Supply in Hazardous Areas

The hermetic industrial socket rated at 400 V and 16 A is a key component of installations in locations where the presence of gases or dusts requires special precautions. Designed for fixed mounting, the device meets rigorous standards for explosion-hazardous zones of type II A (zones 1, 2, 21, and 22), providing flameproof protection type ED. This allows its safe use in the chemical industry, refineries, or construction sites, where standard electrical accessories would be prohibited.

The black housing made of polyamide not only stands out aesthetically but primarily offers high mechanical resistance – the IK08 certification confirms its ability to withstand strong impacts. Such a solution is invaluable in environments where equipment is exposed to falling tools or other mechanical damage. The IP66/67 ingress protection rating guarantees complete protection against dust and the possibility of short-term immersion in water, making it an ideal choice for outdoor work or in humid production halls.

Compliance with Standards and Connection Reliability

A key aspect of this socket is its compliance with the EN 60309-2 standard and specific voltage coding. The red identification color (specified in the standard for 400 V) and the protective contact position marked as "6 h" prevent the connection of an incorrect plug or the use of the device at an inappropriate voltage. For the installer, this means faster and less error-prone work during installation, while for the end user it provides an additional layer of operational safety.

Inside the housing are silver-plated brass (CuZn) contacts with front clamping. This construction ensures low transition resistance and stable current conduction even with frequent connection and disconnection of three-phase loads. Screw terminals enable permanent and secure cable fixation, which is essential at the rated current of 16 A in four-conductor circuits (3P + PE).

Application and Design Features

The device features a very compact design, facilitating installation even in spaces with limited room. The cable entry direction is straight, simplifying cable routing in distribution boards or on walls. The presence of the protective contact and its position indicator are standard safety elements that, in this model, are additionally protected against accidental damage.

Main benefits of using this socket:

• Explosion protection: Certified for use in explosion-hazardous zones II A (type ED).
• Mechanical durability: Polyamide housing resistant to impacts (IK08) and weather conditions.
• Complete sealing: IP67 protection rating guards against dust and water.
• Electrical safety: 400 V / 6h coding prevents incorrect connection.
• Contact durability: Silver plating on brass contacts ensures long service life of the connection.

All key technical data of the device have been discussed above: it operates at 400 V and 16 A, has four poles (3P + PE), and offers an IP66/67 protection rating. The housing is made of plastic (polyamide), and its explosion hazard class is II A, allowing installation in zones 1, 2, 21, and 22. The identification color is black (consistent with voltage coding), and the mounting type is fixed (wall/panel socket). Additional features include impact resistance IK08 and a straight cable entry direction. Thanks to the combination of high-level explosion protection with resistance to external conditions, this socket constitutes a reliable link in industrial power supply systems where safety is the number one priority.
