Receptacle socket (fixed) 16A 3P+PE 400V with cover IP44 514-6D

Power Supply in Challenging Conditions with Impact Resistance

The red fixed plug rated at 16 A and 400 V is a solution dedicated to the safe connection of industrial equipment, construction machinery, and devices requiring three-phase power. Its characteristic color (RAL 3000) and 4-pole configuration (3P+PE) with the protective contact position at 6 o'clock ensure immediate identification and eliminate the risk of incorrect connection. Thanks to the IP44 protection rating, the housing effectively protects against the ingress of solid objects larger than 1 mm and water droplets falling from any angle, making it an ideal choice for production halls, workshops, or construction sites where conditions are not ideal.

The housing is made of durable plastic, featuring high resistance to mechanical impact and tension, which translates into a long service life even with intensive use. A key structural element is the brass (CuZn) screw terminals, which not only ensure stable electrical contact but are also resistant to shocks and vibrations. The mounting system is designed to shorten installation time – simply rotate the housing to secure the accessory without the need for additional tools. This solution will be particularly appreciated by installers working in the field, where speed and reliability are crucial.

Practical Benefits and Universal Application

The plug is designed with compatibility in mind for standard CEE sockets from various manufacturers, facilitating integration with existing electrical infrastructure. The terminals are adapted to standard conductor diameters, and their color coding (green for PE, blue for N, grey for phases) minimizes the risk of errors during cable connection. The lack of need for maintenance and high mechanical strength make this a "install and forget" product.

Thanks to the simple plug insertion direction and solid construction, the device is suitable for circuits with a frequency of 50–60 Hz. It is worth paying attention to several key aspects of using this product: the quick-lock system allows for mounting without tools – simply rotate the housing; vibration-resistant screw terminals guarantee connection stability even when operating motors or vibrating devices; the red housing and clear pole markings facilitate quick inspection of the installation status by technical personnel; the IP44 rating protects against dust and splashes, which is essential in industrial environments.

The contact material (brass CuZn) ensures low current transition resistance and corrosion resistance even in humid environments. The red color of the housing allows for immediate distinction of this device from 230 V (blue) or 110 V (yellow) sockets, which is crucial for the safety of electricians. The screw terminals enable the connection of cables with various cross-sections without the need to purchase special end caps or adapters. Thanks to the IP44 protection rating, the product can be safely mounted in locations exposed to dust or accidental water splashes, such as external construction distribution boards.

The product does not require a phase reverser or additional accessories for basic mounting. Its construction allows operation in extreme temperature conditions typical of production halls or outdoor workstations. This makes it a reliable link in the energy distribution system for professionals requiring certainty of operation for every element of the installation.
