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 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 end caps of the EK series can be used to protect open ends of cut-to-length bars. The EV-S BS touch protection covers unused connections. Properties: - can be used to connect residual current circuit breakers, miniature circuit breakers and FI/LS combinations - large variety of variants - small design, - 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. Installation type: 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 miniature circuit breakers from above in combination with Doepke residual current circuit breakers, the connecting rails EV-SGANL (Nleft) or EV-SGANR (Nright) must be used.
