Key Features

This distribution board is designed for heavy-duty performance and offers several critical advantages for safe and efficient power management.

The board supports the installation of a Schneider NSX 250A MCCB as the incoming main device, allowing for high-capacity circuit protection and disconnection.

It includes 42 outgoing ways, providing sufficient circuit separation and flexibility for complex building systems with multiple loads.

Full compatibility with Schneider’s Acti 9 modular devices ensures seamless integration of miniature circuit breakers (MCBs), residual current devices (RCBOs), surge protection devices (SPDs), and energy meters.

The fully enclosed, touch-safe design and shrouded busbars ensure a high degree of safety during operation and maintenance, reducing the risk of accidental contact or arc faults.

The board’s vertical layout and wide internal space allow for simplified cable routing, easier installation, and enhanced maintenance accessibility.

The robust metal enclosure is treated with a corrosion-resistant epoxy coating, making it suitable for demanding environments.

Applications

This distribution board is suited to a wide range of applications where centralized power control and multiple outgoing circuits are required. Typical use cases include:

• Commercial buildings such as shopping malls, office towers, and hotels

• Industrial facilities and light manufacturing plants

• Healthcare environments including hospitals and clinics

• Educational institutions such as schools and universities

• High-rise residential developments

• Airports, transport hubs, and public infrastructure

• Data centers and technology parks
