Fixed socket 16 A 3P+N+PE 400 V IP44 555159

Professional industrial socket for demanding installations

The 16 A 3P+N+Z 400 V IP44 fixed socket is an element of the P17 Tempra Pro series from Legrand, designed specifically for professional electrical installations in industrial and commercial environments. This is a highly reliable CEE power socket that excels in applications requiring stable power supply for devices with significant power consumption.

Construction and materials ensuring durability

The housing, made of plastic - polyamide 6, is characterized by exceptional resistance to environmental conditions. This material provides IK09 class impact resistance, making the socket resistant to accidental mechanical damage during operation. The design has been tested for glow wire resistance: the live part support withstands temperatures up to 850°C, while the housing withstands up to 650°C.

Compact dimensions (93 × 131 × 139 mm) allow for installation even in limited spaces while maintaining full functionality. The socket features an M25 cable gland, which facilitates cable entry/routing and ensures a tight connection.

Electrical parameters and system compatibility

The device operates within a voltage range of 380-415 V~ at a frequency of 50/60 Hz, making it compatible with most power systems in Europe. The 3P+N+Z configuration (3 phases + neutral + earth) provides full functionality for three-phase devices requiring a separate protective conductor.

The socket is equipped with a single CEE 7/3 (type F) socket with a protective contact, enabling the connection of standard single-phase devices and transition adapters to three-phase systems. Screw terminals are used, guaranteeing a secure and durable connection of wires without the risk of loosening due to vibrations or temperature changes.

Installation and environmental resistance

Designed with easy installation in mind, it includes surface mounting (wall-mounted), which does not require additional holes in walls or specialized tools to close the cover. The "tool-free closure" system significantly shortens installation time and facilitates servicing.

The IP44 protection rating provides an effective barrier against dust and water splashes from all directions, which is crucial in industrial environments where condensation, technological dust, or accidental splashing occurs. The grey housing color is practical—it masks operational dirt and fits perfectly into the aesthetics of most industrial installations.

Regulatory compliance and certification

The product meets the rigorous requirements of international standards IEC/EN 60309-1 and IEC/EN 60309-2, which regulate the parameters of industrial sockets and plugs. Certification confirms full compliance with European electrical safety standards and holds ISO 9001 and ISO 14001 certificates, confirming the highest quality of the production process.
