In energy monitoring, incorrect wiring can destroy current and voltage transformers. Our specially developed test-disconnect terminal blocks, in various connection technologies, are a safe way of solving this problem. Simple operation ensures error-free, convenient wiring. This guarantees the protection of your transformers and measuring devices, and ensures safe, precise work. Our integrated terminal blocks, in modular design for transformer switches, also save space in the panel.
In T&D applications, current and voltage transformers are mainly used for protection and measurement functions. Our new TTB range of Klippon® Connect transformer terminal blocks have been designed to meet all the connection requirements of these two critical applications.
In current transformer circuits, the ATTB 6 PG CT is equipped with a specially designed 2 and 3 pole self-shorting plugable to guarantee a Make Before Break (MBB) contact under every handling condition.
For some technical connection conditions from the German-speaking countries, we offer prefabricated strips according to the respective TAB. You can find an overview of these terminal strips here:
The "TAB NS Nord 22" terminal strip is structured in accordance with the standard wording for technical connection conditions under the title "TAB NS NORD 2019" (TAB 2019). It is responsible for the connection and operation of plants on the low-voltage grid in the area of the BDEW regional group Northern Germany together with the BDEW regional group Berlin/Brandenburg. The terminal blocks are designed with the PUSH IN connection technology. Please always refer to the supplementary sheets of the respective grid operator.
The "TAB NS Nord 14" terminal strip is structured in accordance with the standard wording for technical connection conditions under the title "TAB NS NORD 2019" (TAB 2019). It is responsible for the connection and operation of plants on the low-voltage grid in the area of the BDEW regional group Northern Germany together with the BDEW regional group Berlin/Brandenburg. The terminal blocks are designed with the PUSH IN connection technology. Please always refer to the supplementary sheets of the respective grid operator.
The "VDE FNN" terminal strip is designed in accordance with the "VDE FNN note for meter stations with semi-indirect measurements up to 1000 A in low voltage (for transformer systems)". It refers to version 1.0 from June 2022 and is used to standardize semi-indirect measurements (transformer measurements). This note is to be applied together with VDE-AR-N 4100:2019 and VDE-AR-N 4100 authorization 1:2019. The terminal blocks are designed with the PUSH IN connection technology.
