We do not recommend the use of motors that are operated
in continuous duty with less than 50% of their rated
current.
The rated motor current must not be smaller than 30% of
the rated current of the Soft-Starter, in order that the
overload protection works properly.

Table 3.6 - Maximum current capacity of the power supply
The SSW-03 Plus is suitable for use on a circuit capable of
delivering not more than X Arms (see below) symmetrical
amperes, Y volts maximum, when protected by Ultra-fast
Semiconductor Fuses.
The SSW-03 Plus can be installed on power supplies with a
higher fault level provided that adequate protection is
provided by the fuses or circuit breaker.
