(Subject to alterations. This product is not designed to be used in applications such as life support systems wherein a failure or malfunction could result in injury or death)
The figures 1-1A, 1-1B and 1-1C show all
possible installation variations where
the ESB303 can be used. The neutral
must be connected to the unit. If the
neutral is not connected the ESB303
remains in the limiting mode. If so, the
device will overheat, and the internal
temperature protection will irreversible
blow. The device is powered between
phase conductor and the neutral. Each
phase connection is limited separately
thus a loss or a breakdown of each line is
protected by the ESB303 unit.
The figure 1-1 shows the distribution of
the potentials in relation to the neutral
connection. In three-phase systems, the
effective value of the sinusoidal AC
mains voltage between an outer
conductor and the neutral conductor is
230V, and between two outer
conductors is approx. 400V.
The ESB303 cannot be used in 3-phase
systems without an N-wire. For such
application we recommend the use of
our ESB00163 and ESB00323 inrush
limiters.
