Why ALPHA low-voltage distribution boards?

The modular ALPHA low-voltage distribution boards are available in both DIN and NF versions. They offer solutions for every requirement with wall-mounted, floor-standing, and compact distribution units. Also, they are modular designed for different demands and provide installation kits for simple configuration and assembly. With their compact design, SIMBOX small distribution boards offer maximum flexibility and can be used as either sub-distribution boards or floor-panel boards. The portfolio seamlessly integrates innovative SENTRON devices for protection, switching, measurement, and monitoring. Certified distribution boards and advanced components help ensure high system availability while maintaining the highest standards of safety for both personnel and equipment. Panel builders also benefit from increased efficiency and productivity through data-driven engineering with the SIMARIS create software.

Key benefits

Plan easily and ensure conformity

Plan, configure, and document with the software tool SIMARIS create for simple and intuitive configuration of ALPHA distribution boards. Documentation happens standard-compliant in accordance with IEC 61439.

Speed up installation

All ALPHA distribution boards offer features that clearly simplify installation: Device-specific installation kits, preassembled top-hat rails and quick lock screws or modular installation devices, depending on your model.

Benefit from solutions for every application

ALPHA distribution boards are available as wall- and floor-mounted variants. They cover currents between 125 A and 1,250 A. Thanks to IEC-certified DIN and NF distribution boards, the portfolio can be used in many applications.

Install quickly and efficiently

The ALPHA distribution boards supporting DIN technology are available with device-specific installation kits for a range of different versions to make planning and assembly easier. ALPHA UNIVERSAL distribution board supporting NF technology come with preassembled top-hat rails and quick-lock screws for quick assembly. And the ALPHA SIMBOX small distribution boards simplify preparation with modular installation devices that can be attached to the top-hat rail before the distribution board is installed. Additionally, they come with ample wiring space.

Well prepared for renewables

The demand for photovoltaic systems in Germany is growing rapidly, with more rooftops feeding electricity into the grid. As capacity increases, safe and standard-compliant measurement becomes essential to ensure reliable monitoring and accurate grid feed-in. For a connected load above 30 kW (continuous current > 44 A), DIN VDE 0603-2-1/2 and DIN EN 61439 require energy measurement via current transformers.

ALPHA DIN distribution boards offer a flexible solution using SIMARIS configuration and SIMARIS create to precisely plan and modularly tailor systems to fulfill the specific requirements. New APZ, RfZ, and transformer modules enable optimized configuration from protection and feed-in to secure energy measurement. The distribution boards are well-designed, including safe expansion and easy wiring.
