EX plug-in devices, explosion-proof, current-carrying part - socket - 400V, 16A, 5P IP66/67 2514017

Safe Power Supply in Explosive Hazard Zones

This is a fixed EX-type socket designed for operation in environments where the presence of gases or dusts requires special caution. The device handles 400 V circuits and currents up to 16 A, making it a versatile component for many industrial installations. Key to its application is compliance with requirements for zones 1, 2, 21, and 22 thanks to explosion protection type ED. In practice, this means that even under intensive use in harsh conditions, the risk of sparking leading to an explosion is eliminated by the design.

The housing made of polyamide not only protects the interior against dust and water (IP66/67 rating) but also withstands mechanical impacts of class IK08. This is crucial for installers working in production halls or outdoors – the device will not crack from accidental tool impact or dropping. Inside, you will find silver contacts with front clamping, which ensure low transition resistance and connection stability even under high inrush currents.

Application and Key Design Features

The device is intended for surface mounting in locations requiring frequent connection and disconnection of power for portable or fixed equipment. Thanks to 5 poles (including the protective contact) and a "6 h" position indicator, the socket guarantees correct connection sequencing, which is critical for operator safety. The cable entry direction is straight, facilitating installation in tight spaces or when using standard cable glands.

It is worth noting several specific solutions that distinguish this model:

• Contact material: Zinc-plated copper (CuZn) with nickel plating (according to source data) or raw state (depending on the version), ensuring corrosion resistance and good conductivity.
• Mechanical locking: Prevents accidental disconnection of the plug under voltage or its self-ejection during device operation.
• Color scheme: Red housing (in accordance with EN 60309-2 for 400 V) allows quick voltage identification by technical personnel.
• Compactness: A very compact housing enables mounting even where space is limited, while maintaining full IP67 sealing.

Compliance with Standards and Operating Conditions

The product meets rigorous safety requirements for explosive hazard zones (hazard class II A). It operates stably at ambient temperatures typical for industrial environments, and its IP67 sealing allows operation underwater for short periods or in conditions of heavy rain and dust. Installation is simple thanks to standard screw terminals and the possibility of direct cable entry through the gland.

Summarizing key operational data: the device operates at 400 V with a current of 16 A, has 5 poles, and an IP protection rating of IP66/67. Its mechanical strength is IK08, and the housing material is polyamide. The cable entry direction is straight, facilitating installation in hard-to-reach locations. Thanks to the combination of a solid polyamide construction with silver contacts, the device offers long service life even with frequent connection cycles. This is a solution dedicated to applications where explosion-proof safety goes hand in hand with electrical reliability.
