EX plug-in devices, explosion-proof, current-carrying part - socket - 230V, 16A, 3P IP66/67 2514015

Safe Power Supply in Hazardous Areas

This EX-series socket is designed for use in environments where there is a risk of explosion from gases and dusts. The device supports 230 V circuits with a rated current of 16 A and features three poles, corresponding to a standard three-phase connection without a neutral conductor (L1, L2, L3 + PE). With an explosion hazard classification of IIA and approval for zones 1, 2, 21, and 22, it can be deployed where flameproof protection type ED is required.

The housing is made of polyamide, a material characterized by high mechanical and chemical resistance. An IP67 protection rating ensures dust tightness and protection against temporary immersion in water, making it suitable for outdoor or industrial applications under harsh atmospheric conditions. IK08 impact resistance further enhances durability against mechanical damage during transport or installation.

Construction and Mounting Details

A key structural element is the silver-plated contacts equipped with front clamping. This design ensures low contact resistance and stable connections even under high inrush currents or load fluctuations. The cable entry direction is straight, simplifying cable routing in distribution boards or for portable installations.

Note the color coding:

• The housing is black (as per catalog data), providing clear visual segregation of the installation.
• The voltage of 230 V (50+60 Hz), in accordance with EN 60309-2, is typically indicated by blue (RAL 5017); although this unit has a black housing, the voltage parameter remains compliant with the standard for this class of equipment.
• The protective contact position indicator is precisely set at the 9 o'clock position.

Key technical parameters of the device: rated current 16 A at 230 V mains voltage. Number of poles: 3P + PE. Protection rating: IP67. Housing material: plastic (polyamide), resulting in IK08 impact resistance. The unit meets requirements for explosion zones 1, 2, 21, and 22 when used with ED-type protection.

Applications and Benefits for the Installer

This device is ideally suited for the chemical and petrochemical industries, as well as storage areas for flammable materials. For the installer, it enables quick connection of portable electric tools (e.g., drills, grinders) without the need for additional anti-explosion safeguards—the socket's construction itself fulfills safety requirements.

Thanks to its compact design, it occupies minimal space in distribution boards or on mounting walls. Screw terminals allow secure fixation of conductors with appropriate cross-sections. The CuZn contact material, silver-plated, minimizes corrosion risk and ensures long-term reliability of electrical connections even in humid environments. This solution is dedicated to applications where fire safety is a priority and operating conditions require resistance to dust and water.
