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. Contact protection is required by end capping the EK series. Unused connections can be covered by the EV-S BS protective cover.
