Circuit breakers
The SACE Emax 2 low voltage power circuit breaker
includes spring-operated, stored energy, close
and trip mechanisms for either manual or
electrical operation.
SACE Emax 2 circuit breakers form the complete
family of breakers used in ReliaGear LV SG. Each
type of breaker listed in Table 2 describes the
breaker interrupting rating which corresponds to
the 3rd digit of the breaker catalog number. These
circuit breakers, in a compartment, range from 800
to 5,000 amperes.
