The
TZS-100 Zero Phase Current Transformer is built to support
very high current applications up to 992A, making it ideal for large industrial panels, substations, and power distribution systems. Designed for
3-phase 4-wire electrical networks, it accurately detects leakage currents when paired with
TERASAKI TZS-AD earth leakage relays.
Featuring a large 100mm internal diameter, the TZS-100 easily accommodates multiple heavy conductors up to 600 mm², ensuring smooth installation in high-capacity panels. Its robust insulated housing provides excellent electrical isolation, durability, and stable operation even in demanding environments.
Backed by TERASAKI’s trusted engineering standards, the TZS-100 Z-CT enhances operational safety, reduces risk of electrical faults, and offers peace of mind for critical power systems.
