Overview
The ZCT series are compact, molded-type, zero-
phase current transformers. They are ideal for
improving the sensitivity, compactness, and weight
of electric shock prevention.
Applications
Typical applications include electric shock prevention from
earth leakage breakers, short-circuit relays, and ground fault
circuit interrupters.

Current Sensors – ZCT, Zero-Phase Current Transformers
Handling Precautions
Precautions for Product Storage
Current sensors should be stored in normal working environments. While the sensors are quite robust in other
environments, exposure to high temperatures, high humidity, corrosive atmospheres, and long-term storage
degrade solderability.
KEMET recommends that maximum storage temperature not exceed 40°C and maximum storage humidity not exceed 70%
relative humidity. Atmospheres should be free of chlorine and sulfur-bearing compounds. Temperature fluctuations should
be minimized to avoid condensation on the parts. Avoid storage near strong magnetic fields, as they can magnetize the
product and cause its characteristics to change.
For optimized solderability, the stock of current sensors should be used within 12 months of receipt.
Before Using Zero-Phase Current Transformers
Do NOT drop or apply any other mechanical stress, as such stresses may change performance characteristics.
Do NOT use current transformers opened between secondary output terminals. Heat build-up in the magnetic core may
occur, resulting in damage to the parts by coil melting.
If the ZCT series is used as a current transformer, contact KEMET for more information.
Export Control
For customers in Japan
For products that are controlled items subject to the “Foreign Exchange and Foreign Trade Law” of Japan, the export license
specified by the law is required for export.
For customers outside Japan
Sensors should not be used or sold for use in the development, production, stockpiling or utilization of any conventional
weapons or mass-destructive weapons (nuclear weapons, chemical or biological weapons, or missiles), or any other
weapons.
