EX plug-in devices, explosion-proof, current-carrying part - plug - 230V, 16A, 3P 2518015

Safe Power Supply in Hazardous Areas

This device is a specialist industrial plug designed for operation in environments where standard electrical solutions may pose a hazard. It is intended for connecting equipment rated at 230 V and 16 A in explosive atmosphere zones of class IIA (zones 1, 2, 21, and 22). Thanks to the use of increased safety type 'e' (ED) protection, this component meets rigorous safety requirements in locations where explosive gas or dust atmospheres may occur.

A key structural element is the very compact housing made of polyamide. This material not only ensures resistance to weather conditions but also features high mechanical strength, confirmed by impact resistance class IK08. This means the device can withstand accidental impacts or drops during transport and installation. Inside, silver contacts with front pressure are used, ensuring a stable electrical connection and minimizing the risk of contact overheating under prolonged load.

Application and Ease of Installation

The plug is widely used in the chemical, petrochemical, and processing industries, where safe power supply for portable machinery and tools is required. The cable entry direction is straight, facilitating cable routing even in tight spaces. Installation is performed via screw terminals, allowing connection of conductors with a cross-section from 1 to 2.5 mm². A clamping force of 100 Ncm ensures a secure connection without the need for additional measuring tools during each installation.

For the installer, the functionality of the installation process itself is also important:

• Quick Connection: Screw terminals are compatible with standard electrical tools.
• Safety: The presence of a protective (grounding) contact with a position indicator at the "9 h" position allows visual verification of correct installation before initial commissioning.
• Durability: Contacts are nickel-plated, increasing their resistance to corrosion and oxidation in harsh environmental conditions.

Compliance with Standards and Visual Identification

The product is manufactured in accordance with EN 60309-2 for a voltage of 230 V (frequency 50+60 Hz). Visually, it is distinguished by its blue color (in accordance with the color code for 230 V), which facilitates quick identification of the voltage type in complex industrial installations. The housing is black (in visible identification parts), and the IP44 protection rating guards against direct water spray and solid objects larger than 1 mm.

Key technical data of the device include: rated current 16 A at mains voltage 230 V, number of poles 3, and explosive atmosphere class IIA. The housing is made of plastic (polyamide) in black color, corresponding to the standard for this type of equipment. The cable entry direction is straight, and the presence of the protective contact is confirmed by a position indicator at 9 o'clock. The device also carries compliance marking for voltage 230 V (50+60 Hz) in blue color according to EN 60309-2.

This device constitutes a robust element of the power supply system where explosion-proof safety is a priority. Its compact design allows installation in areas with limited space and high mechanical strength requirements. Thanks to silver contacts and a precise front-pressure construction, it ensures reliable operation even with frequent connection and disconnection of working equipment.
