EX plug-in devices, explosion-proof, current-carrying part - plug - 400V, 16A, 5P 2518017

Safe Power Supply in Hazardous Areas

An industrial plug 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. The device is designed for operation in explosion hazard zones of class IIA (zones 1, 2, 21, and 22). This allows its safe use when connecting machinery and equipment in environments requiring explosion protection type ED.

The housing, made of polyamide, features a very compact design, facilitating installation even in hard-to-reach places. This material not only ensures resistance to atmospheric conditions but also high mechanical strength – impact resistance class IK08 guarantees that the device will withstand accidental impacts during transport or operation. The housing color (black) and voltage identification (red according to standard EN 60309-2) allow technical personnel to quickly identify the connector parameters.

Construction and Connection Reliability

Inside the housing are silver contacts equipped with a front-pressure system. This construction ensures stable electrical contact even under high inrush currents or vibrations occurring in industrial environments. The number of five poles (5P) and the presence of a protective contact (grounding) are essential for the safe power supply of three-phase devices with a protective neutral conductor.

The cable entry direction is straight, simplifying the final assembly process on the power cable. The cable gland allows for secure cable fixation, and the IP44 protection rating protects the interior against solid objects larger than 1 mm in diameter and against water splashes from any direction. Thanks to this, the plug is suitable for use both in production halls and in outdoor areas.

Application and Benefits for the Installer

The device is dedicated to applications requiring high reliability in harsh environmental conditions. Installers will appreciate the ease of installation thanks to screw terminals and the precise construction of contacts, which minimize the risk of joint overheating.

Main product advantages:

• Explosion protection: Certified for operation in IIA zones (type ED), eliminating the risk of igniting the surrounding environment during device operation.
• Mechanical durability: Polyamide housing with IK08 impact resistance class, resistant to impacts and mechanical damage.
• Electrical stability: Silver contacts with front pressure ensure low transition resistance and long-term operation without loss of conductive properties.
• Environmental versatility: IP44 protection rating allows safe operation both indoors and outdoors, regardless of weather conditions.
• Easy identification: Red color according to standard EN 60309-2 clearly indicates 400 V (50/60 Hz) voltage, and the protective contact position indicator (6 h) facilitates proper insertion of the plug into the socket.

Parameters such as rated voltage 400 V and current 16 A define the application range for medium-power three-phase devices. The number of five poles and explosion hazard class IIA determine the possibility of installation in zones 1, 2, 21, and 22 while maintaining protection type ED. Housing durability IK08 and protection rating IP44 guarantee resistance to external factors and mechanical damage during daily industrial operation. The straight cable entry direction simplifies the installer's work during final connection of the cable to screw terminals.

Thanks to the combination of rigorous safety standards with practical design, this model constitutes a solid solution for industrial installations requiring continuous power supply in explosion hazard conditions.
