(1)
With phase-to-phase voltage V greater than 690 V AC rated voltage (maximum 760 V AC), in the presence of
external sockets and an isolation transformer.
(2) The measurement of the frequency is available with a a phase-to-phase voltage value ≥ 36 V AC, and is
unavailable with a phase-to-phase voltage value ≤ 32 V AC.
(3)
In the absence of harmonic distortion.
connected to a connector, to which the phase and neutral voltages arrive either on the internal contacts of
the circuit-breaker, or on the external sockets.
Information on the assembly is available on the website http://www.abb.com/abblibrary/DownloadCenter/, in
particular in the kit sheet 1SDH001000r0505.
IMPORTANT: in the case of dielectric tests, you need to disconnect the modules as
illustrated in the assembly diagram, and to disconnect the external sockets from the
terminal box. It is not necessary to remove the modules.
An example with an E2.2 circuit-breaker in fixed and withdrawable versions is provided to the side.
The following is a view of the terminal box of E1.2 and E2.2-E4.2-E6.2 circuit-breakers with the relevant wiring
