Power Metering CTs
Product Overview
H681x-xxx 5 Amp split-core current transformers (CTs) provide secondary amperage proportional to the primary
(sensed) current. For use with power meters, data loggers, chart recorders, and other instruments, the H681x
Series 5 Amp CTs provide a cost-eective means to transform electrical service amperages to a 0 to 5 Amp level
compatible with monitoring equipment.

1. Disconnect and lock out power to the primary circuit before installing these CTs.
2. Connect the secondary leads to the burden or test switching/shorting bar. The white wire is the X1 lead.
3. Depress the tabs on one end of the CT to open it. Check the core ends on both sections of the CT to ensure there is no rust or
debris in the closure areas.
4. Slip the CT over the primar y leads. Note labeling on the product indicating “source side.”
5. Close and latch the CT, and mount it securely.
6. In any application where fault currents can exceed 20 times rated current of CT, use wire ties or similar fasteners to secure the
I-bar to the CT housing (see below). Secure both sides of the I-bar.
Secure the I-ba r with a wire tie in
applicatio ns where a fault current
could exceed 20x rated cu rrent.
7. Reconnect power to the panel.
An optional mo unting kit is available for th ese devices (Veris part number AH 06).
Ratings
These products provide basic insulation to 600 VAC between the sensed conductor and the output leads. For reinforced
applications, the installer must provide appropriate insulation. Reinforced insulation is provided for applications to 300 VAC
between the sensed conductor and the output leads.
