Product Description
External current transformer installed at the transformer neutral-to-ground bonding conductor (star-point grounding) to measure ground return current (G_ret) during earth faults. The secondary signal connects to the ETU660 LSIG trip unit in Siemens 3WL10 air circuit breakers and 3VA27 moulded case circuit breakers, enabling ground-fault return protection — complementary to residual-current detection via summation CT.
Key Features
- 100 A primary rated current for ground return measurement at transformer neutral
- Designed for ETU660 LSIG trip units with G_ret protection function
- Compatible with 3WL10 (up to 1250 A) and 3VA27 (up to 1600 A) circuit breakers
- Ambient temperature range: -25 °C to +70 °C
- RoHS compliant, made in Italy
