about us
PROCONECT is a French manufacturer specializing in the design, development, and production of heavy-duty industrial connectors, distribution boxes, and cable assemblies. As a trusted partner for heavy industries, we deliver robust, highly reliable connectivity solutions engineered to perform flawlessly in the most demanding environments.
The railway sector is at the core of our DNA. We develop a comprehensive range of high-power electrical connectors for fixed and on-board installations, equipping trains, subways, and trams worldwide. Deeply involved in the technical evolution of our industry, PROCONECT acts as a key technical advisor within international working groups. Notably, we are an active member of the CENELEC WG19 committee, helping to shape the EN 50546 European standard for shore power supply systems and connectors dedicated to railway vehicles.
Our solutions are designed to solve the concrete challenges faced by operators and rolling stock manufacturers. We provide ultra-robust shore power connections for maintenance depots (stinger systems), ensuring seamless interoperability for powering auxiliary systems and pre-conditioning trains before they enter commercial service. Our expertise also covers high-capacity inter-coach connections (Head End Power / HEP) with optimized mobile plugs and fixed sockets capable of handling up to 800 A and 1.1 kV, alongside custom track-side distribution boxes.
Beyond our standardized ranges, our in-house design office supports clients with custom connector development and retro-engineering services tailored to strict technical specifications. To guarantee uncompromising quality and maximum safety, we rely on our fully integrated testing laboratory. This facility allows us to conduct extensive pre-validation trials—including insertion cycles, watertightness checks, and overheating tests—long before official certification.
Proud to be trusted by global railway leaders such as Alstom, SNCF, RATP, Siemens, and Wabtec, we design our products with a deep commitment to sustainable excellence. We are fully ISO 9001 and ISO 14001 certified, and have recently been awarded the EcoVadis Gold medal for our CSR performance. Choose PROCONECT for safe, innovative, and durable railway connectivity that powers the future of your infrastructures.

Discover the 3PX3, our flagship connector fully compliant with the European EN 50546 standard for three-phase shore power supply systems. Designed for 63/125 A and 400 V AC applications, it guarantees perfect interoperability for railway vehicles in maintenance depots. Built to perform in harsh environments from -40°C to +120°C, the 3PX3 features a rugged cast aluminum AS7G casing ensuring IP66 watertightness and IK10 impact resistance. Equipped with an EN 45545-2 compliant PBT insert for optimal fire safety, it is the ultimate choice to reliably power auxiliary systems and pre-condition trains before their commercial service.

Beyond the 3PX3, PROCONECT engineers a comprehensive range of heavy-duty connectors dedicated to diverse stinger applications. These shore power solutions are vital for powering non-traction equipment like HVAC and ensuring train pre-conditioning. For high-capacity needs, our lineup features the 3PXU and 3PU single-pole connectors, capable of handling up to 800 A and 1.5 kV with IP67 watertightness. We also provide the bipolar 3P2U connector, rated for up to 250 A and 1 kV. Housed in durable AS7G cast aluminum, these connectors deliver exceptional impact resistance for safe and highly reliable maintenance depot operations worldwide.

For safe and efficient power distribution across rolling stock, our Head End Power and coach-to-coach connections deliver unmatched reliability. This specialized range highlights the 3PX4 connector rated for up to 250 A and the high-capacity 3PX5 handling up to 500 A, both operating safely at 1.1 kV. Encased in tough AS7G cast aluminum, they provide superior IP67 protection and IK10 impact resistance in harsh conditions from -30°C to +60°C. These engineered plug-and-socket solutions protect the cable environment and can be customized with optimized fuse distribution or microswitches to easily capture critical connection and disconnection data.
