AT series distribution
AT series distribution boards are modular enclosures designed for housing and protecting electrical distribution components such as miniature circuit breakers (MCBs), residual current devices (RCDs), and busbars.

AT series distribution boards are modular enclosures designed for housing and protecting electrical distribution components such as miniature circuit breakers (MCBs), residual current devices (RCDs), and busbars. These boards typically feature a rated insulation voltage of up to 690V AC, with current ratings ranging from 63A to 250A depending on the configuration. They are constructed from high-grade thermoplastic or sheet steel, offering IP ratings from IP30 to IP65 for indoor or outdoor use. The modular design allows for easy installation of DIN-rail mounted devices, with options for single-phase or three-phase (3P/4P) configurations. Common pole configurations include 2P, 4P, and 12-way to 36-way layouts, supporting both main switch and RCD incomer options.
These distribution boards are widely deployed in residential, commercial, and industrial electrical installations. Typical applications include final distribution in apartment buildings, lighting control panels in offices, power distribution in small workshops, and automation cabinets in manufacturing facilities. They are also used in renewable energy systems, such as solar photovoltaic (PV) arrays, where they house DC and AC protection devices. The enclosures are suitable for surface mounting or flush mounting in walls, and can be integrated into building management systems (BMS) for remote monitoring.
The AT series includes several subcategories such as the AT1, AT2, and AT3 ranges, each tailored for specific load capacities. Key article codes include AT1-12 (12-way, 63A main switch), AT2-24 (24-way, 100A RCD incomer), and AT3-36 (36-way, 250A main switch). The coding typically follows the pattern AT[series]-[number of ways]-[incomer type], where the series number indicates the physical size and current rating. For example, AT1-12-M indicates a 12-way board with a main switch, while AT2-24-R denotes a 24-way board with an RCD incomer. These boards are compatible with a wide range of accessories, including busbar kits, neutral bars, and gland plates.
