as manual motor controllers and are suit-

able as motor disconnects. They are load

break rated and act as enclosure discon-

nects when short circuit protection is

provided upstream of the switch. If

upstream over current protection is not

provided, use a Siemens fusible Type

VBII, CFS or MCS Disconnect Switch.
