These components for wiring circuit breakers in industrial, commercial and private electrical distribution boards significantly reduce the installation effort. These cut-to-length busbars are suitable for the supply-side connection of residual current circuit breakers, miniature circuit breakers and FI/LS combinations on the underside of the devices. The rails are fork-shaped and are available in a wide variety of versions in one to four-pole versions (some with space for auxiliary switches). Contact protection using end caps from the EK series is required. The EV-S BS contact protection covers unused connections. Properties: can be used to connect residual current circuit breakers, miniature circuit breakers and FI/LS combinations, wide variety of versions, high time savings when wiring, total length approx. 1000 mm, can be cut to length, insulation of the open ends using optional 'EK' end caps is recommended, type of installation: the rails are plugged into the upper or lower connection terminals of the devices to be connected. Areas of application: Busbars in this series are used in conjunction with RCCB, MCB and RCBO in power supplies for residential and commercial buildings as well as industrial plants. Notes: When feeding in circuit breakers from above in combination with Doepke residual current circuit breakers, the connecting bars EV-S G ANL (N left) or EV-S G ANR (N right) must be used.
