ABB power distribution box 78 positions

ABB's S-series distribution boards can accommodate up to 78 modular positions, offering flexible, safe, and high-quality power distribution for commercial and industrial installations.

Key Features

Modular Design: The ABB S-series distribution boards are designed to house multiple modular devices such as MCBs, RCCBs, RCBOs, and isolators. A 78-position board allows for extensive circuit segregation and customization according to installation needs . Busbar and Electrical Capacity: These boards come with 100A tinned electrolytic copper busbars, neutral and earth bars, and support single-phase or three-phase configurations. They provide per-phase isolation and can handle incomers up to 250A . Safety and Compliance: The boards feature double-door construction, intermediate plates to prevent exposure to live parts, and comply with IEC, UL, and CSA standards. Removable top and bottom gland plates with knockouts allow safe and convenient cable entry . Installation Flexibility: ABB distribution boards can be flush or wall-mounted, with adjustable mounting options. The modular blocks eliminate the need for plate or rail mounting, reducing assembly time by up to 80% compared to conventional systems . Configuration Tools: ABB provides a Power Distribution Scheme Creator, which allows users to select products and assign them to specific positions in a matrix. This tool simplifies planning for a 78-position board, including circuit labeling, power ratings, and cable specifications . Durability: The boards are made from CRCA steel sheets, undergo a seven-tank phosphating process, and are finished with premier powder coating for corrosion resistance and long-lasting strength .

Practical Considerations

• Circuit Planning: With 78 positions, you can configure multiple single-phase and three-phase circuits, ensuring flexibility for future expansion.
• Safety: Intermediate plates and touch-proof modular blocks ensure no live parts are exposed during operation or maintenance.
• Documentation: ABB provides manuals and datasheets for all distribution boards and modular devices, which can be downloaded for detailed specifications and installation guidance . This combination of modularity, safety, and configurability makes ABB's 78-position distribution boards suitable for complex commercial or industrial electrical installations, providing both reliability and ease of maintenance.
