is ”ON”. Design provides interlocked connect and disconnect
operation as well as short circuit and thermal time delay
overload protection.

• Circuit Breakers are thermal-magnetic type – 150 Amp frame
size, 20 to 100 Amp trip.
Options
• Special Polarization: Prevents plug insertion in a receptacle or
connector wired for a different voltage. In installations where
there are different line voltages, the special polarization option
is desirable. This allows only plugs and receptacles wired for
the same line voltage to be mated together. The receptacle
or connector interior is positioned 22-1/2°, relative to the
polarization rivet, to the right (as specied) of standard, and
plug is polarized to correspond. This option can be added to
receptacles using the Powertite™ Plug. Sufx -PR to receptacle
or plug.
