Simpson’s terminal-type current transformers can be used
to monitor AC Current when the current level is too high for
the panel meter to be connected directly in series, usually
above 75 Amperes. The current transformer reduces the
primary input current to a secondary current of 5 Amperes,
which can be monitored by the panel meter.
The current transformer is equipped with terminals to per-
mit easy connection to either an analog or a digital panel
meter. These terminals are # 8-32 brass studs and come
with flat washer, lockwasher, and regular nut (Leads are not
provided).
A typical wiring setup is shown at right, depicting a termi-
nal-type current transformer installed with a panel meter to
monitor current.
Reduces High AC Current Signal to 5 Amp AC Signal
