Simpson’s Portable and Switchboard shunts
enable a panel meter to indicate higher DC cur-
rents than can be provided with a self-con-
tained internal shunt. A typical shunt installation
in series with the load and source is shown in
the application section.
These shunts can be used with either digital or
analog meters. Most digital DC millivolt meters
that Simpson manufactures can be scaled to
display the actual current. Simpson can custom
design any dial for the analog meters you
require. Simpson manufactures two types of
external shunts: Portable and Switchboard
shunts.

Typical Application
A motor is connected to a
220 Volt power generator,
and running requirements
call for 100 Amps.
motor is attached to an
elevator, and the heavier
the weight in the car the
higher the current draw.
There is a need to monitor
the current draw of the
motor to insure that an
overweight car is not
moved and the motor
damaged.
A break is made in the
common line between the

A shunt with a
Portable shunts are mounted in a phenolic
base. This base allows the shunt to be easily
installed in many locations. Portable shunts
come in a 50 millivolt drop and a 100 millivolt
drop. The most commonly used is the 50 milli-
volt unit.
Switchboard shunts mount directly onto a buss
bar and have a 50 millivolt drop. They have the
same quality construction as a portable shunt,
but without the phenolic base.
Leads for these shunts are 5 feet long and are
rated at 0.065 ohms resistance. Shunts with a
100 amp rating and below can be certified to
NIST standards.
