The busbars of this series can be cut to length and are designed for the supply-side connection of residual current circuit-breakers (RCCBs) DFS 2 or DFS 4, miniature circuit-breakers (MCBs) and residual current operated circuit-breaker with integral overcurrent protection (RCBOs) on the bottom side of the devices. The bars with furcated cable lug are available in a wide range of variants in one to four-pole design (some also with space for auxiliary switches) and provide time-saving and user-friendly processing options. End caps from the “EK” series allow the covering of open ends of bars that have been cut to length. Unused connections can be covered by the EV-S BS protective cover.
