N-Disconnection with N-Disconnect Slide Link or N-Busbar

MM-20032_GWA_IEK_Series_2203_2205_WAGO6483_2000x1125

Circuit Configuration with N-Busbar

WAGO’s 2x03 and 2x05 Series Multilevel Installation Terminal Blocks with N-disconnect slide links are designed for N-disconnection using an N-busbar. The N-busbar can be connected automatically and permanently to the busbar by simply pushing on the screwless N-disconnect slide link. Available in different variants, these terminal blocks cover all practical applications and are especially suitable for the electrical installation of large circuit groups in buildings.

This Model’s Benefits for You

  • Maximum Current Carrying Capacity
    WAGO’s multilevel installation terminal blocks support a wide range of applications and ensure a high degree of electrical safety. Therefore, the 2x03 Series Multilevel Installation Terminal Blocks with N-disconnect slide links can be loaded with a maximum rated current of 32 A.

  • Maximum Touch-Proof Safety
    The busbar’s transparent cover protects the busbar against accidental contact and makes it easy to see if the N-disconnect slide links are connected to the busbar.

  • Maximum Wiring Space
    WAGO’s 2x03 and 2x05 Series Multilevel Installation Terminal Blocks provide all the functionality of a 4 mm2 (12 AWG) or 6 mm2 (10 AWG) terminal block in an extremely compact housing, maximizing connection space in standard distribution cabinets. This compact design offers plenty of space for wiring.

  • Maximum Performance for Large Loads
    WAGO’s 2x05 Series Multilevel Installation Terminal Blocks are ideal for connecting large loads. They are designed for conductor sizes up to 6 mm2 (10 AWG) and a maximum rated current of 36 A.

For Circuits without an N-Busbar

WAGO’s 2x03 Series Multilevel Installation Terminal Blocks with internal N-disconnection are designed for circuits without an N-busbar. Available in different variants, these terminal blocks are ideal for wiring smaller circuit groups, e.g., in installations with multiple ground fault potentials.

This Model’s Benefits for You

  • Insulation Resistance Measurement – Fast and Safe
    WAGO’s N/L test plug adapter is designed for multilevel installation terminal blocks with internal N-disconnection for mounting without an N-busbar. This innovative adapter combines the two live conductors – L and neutral – and thus automatically ensures the fast and safe insulation resistance measurement required by DIN VDE 0100-600.

  • Multilevel Installation Terminal Block with Single-Fuse Plug
    WAGO’s multilevel installation terminal block features a DIN-rail-centered slot that can also be used for TOPJOB® S Single-Fuse Holders (2004-911) for microfuses (5 × 20 mm). In combination with 1 mm thick end and intermediate plates (2x03-6693), carrier terminal blocks can be used as fuse terminal blocks in a standard distribution board’s cutout.

  • Multilevel Installation Terminal Block with Double-Fuse Plug
    WAGO’s double-fuse plug is designed for applications requiring both L and N protection, or those in which a single fuse circuit can be used to protect two circuits and save space.
