Double-deck terminal block
18 September 2013
Interconnection
The new TOPJOB S double-deck terminal block from Wago provides the option of combining the functions of the top and lower levels. The top level, for example, can be used as a disconnect and fuse terminal block, while the lower level can act as a through or ground conductor terminal block. This flexibility makes it well suited for common control cabinet configuration or for process metrology.
The 5,2 mm wide double-deck terminal blocks are designed for 24 A (with a 16 A disconnect function) and for 400 V based on IEC and for 300 V based on UL. The disconnect terminal block version is equipped with a disconnect link in the top level, while the version with the same profile, designed as a fuse terminal block, has a pivoting fuse holder (for 5 x 20 mm fuses).
Other versions include the double-deck through terminal block and the four-conductor double-deck terminal block with internal commoning. Since they have the same profile, the double-deck terminal blocks can be commoned horizontally with other TOPJOB S rail-mounted terminal blocks: the lower potential level with triple-deck terminal blocks and the top potential level with double-deck terminal blocks.
TOPJOB S covers a range of wire sizes from 0,14 mm² to 95 mm² (AWG 24-4/0) and features power cage clamp technology. It is suitable for all types of conductors: solid, stranded and fine-stranded. Conductors with ferrules can also be connected simply by pushing them in. The rail-mount terminal block system has a fast and economical marking system, as well as a comprehensive jumper system.
