The preassembled transformer terminal block with N and PE connection measures voltage in a 3-phase system. The 3 phases and the N terminal block are color-coded with yellow (L1), green (L2), purple (L3) and blue (N).
The test-disconnect terminal blocks offer a high degree of convenience for all the necessary test circuits in secondary current transformer circuits. With six universal function shafts, the test-disconnect terminal blocks provide the highest level of functionality and flexibility in potential distribution.
