These components for wiring circuit breakers in industrial, commercial and private electrical distribution boards significantly reduce the installation effort. The pre-cut 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 bars are designed in a fork design and are available in a wide variety of versions in one to four-pole versions (some with space for auxiliary switches). 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, type of installation: the bars 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.
