Two S&C Current Sensors and one S&C Current/

Voltage Sensor are included on each Scada-Mate

Switch to provide three-phase monitoring of line

current and single-phase monitoring of system

voltage. Sensors for three-phase voltage sensing are

optionally available. Voltage sensors can also be

provided on both sides of the switch for designated

normally open points on the system. All sensors

are of molded S&C Cypoxy

construction and

serve as support insulators for the switch live parts,

thereby eliminating the cost, clutter, and complexity

associated with separately mounted sensors.

The voltage sensor, moreover, provides continuous

battery-charging power for operating the complete

automated-distribution switch installation. There’s no

need to install a separate distribution transformer to

provide low-voltage control power.

Visible air-gap isolation of switched-open circuits—

needed only when work on the feeder is required—is

provided by an integral, hookstick-operated three-pole

disconnect. This novel feature eliminates the need for

separate single-phase disconnects and is much more

convenient to use. An auxiliary switch is provided for

local and remote indication of disconnect position.

Switches in the upright, tiered-outboard, and pole-

top mounting configurations feature an operating

mechanism with a manual-operation pull-ring,

which permits non-electrical mechanical closing and

opening of the interrupters in the event of a power

loss. Switches in the vertical mounting configuration,

on the other hand, feature an operating mechanism

which permits only nonelectrical mechanical opening

of the interrupters.

No other switching device on the market

provides so many features and functions in one

compact package.

Clean and uncluttered appearance . . . sensors,

control power source, and a three-phase disconnect

are built-in.
