Non-Reversing
Mounted in the Medium Voltage Section
●
Three incoming line connectors.
●
One drawout 3-pole gang-operated line isolation switch assembly
with isolating shutter, external operating handle interlocked to
prevent opening the medium voltage compartment door until the
isolating switch is open and grounded.
●
