CUTLER-HAMMER 24kV Type W-VAC Circuit Breaker
SECTION 2: SAFE PRACTICES

2-1 RECOMMENDATIONS

Type W-VAC Vacuum Circuit Breakers are
equipped with high speed, high energy
operating mechanisms. They are designed
with several built-in interlocks and safety
features
to
provide
operating sequences. Cell interlocks used
with drawout circuit breakers are meant to
interact with the appropriate cell interface
and levering mechanism.
