Schneider ZCT-035-Z | zero phase current transformer for EOCR – ZCT-035 – 200 / 1.5 mA

Schneider ZCT-035-Z | zero phase current transformer for EOCR – ZCT-035 – 200 / 1.5 mA

General Description:

The Schneider ZCT-035-Z is a zero phase current transformer (ZCT) designed specifically for use with EOCR (Electronic Over Current Relay) systems. It detects leakage or residual currents by monitoring all three-phase and neutral conductors passing through its core. This model offers a transformation ratio of 200 / 1.5 mA, ensuring accurate and sensitive detection of ground faults.
