Terminal block
PTR-Messtechnik
The strict VDE requirement imposed on ground connections, such as low contact resistance, corrosion-free connection points, secured screws, green-yellow colour coding and clear circuit identification - are fully oberserved by the PTR earth terminal blocks. Mounted on the same DIN RAIL with other types of terminals, are easily distinguished by their green-yellow colour code.
For special emphasis the earth terminal blocks consist of an enclosed green-yellow half shell insulated body made of Polyamide 6.6. Incoming and outgoing earthed conductors have a separate connection point. The structural design of the earth terminal blocks is based on the fact that the mounting rail is used not only mechanically, also electrically, i.e. as a ground (PE) busbar. Therefore it is possible to position the earth terminal blocks directly next to the phase conductor terminals. Earth terminal blocks offer the same space savings and design features as the other PTR terminal blocks and the general terminal marking system can be used.
