The Legrand stepped bar modular distribution block make it possible to a safe and fast bipolar or tetrapolar distribution. Complies with the standard EN 60947-1, they combine electrical performance and mechanical robustness, but also ergonomics to facilitate the implementation of this component key to electrical distribution systems. Thanks to a maximized wiring space, an orientation of the bars optimized and dimensioning of the screw connections adapted, the wiring and the connection is facilitated. In addition, the arrival and departures of large sections are staggered between each rung to avoid overlapping large conductors.

Maximized internal space and optimized rung orientation for easy cable access
Connections sized and positioned to facilitate connection and meet all needs
An "anti-loss of screw" system slowing down the unscrewing of the screws of the unconnected connections
