• Performs continuous monitoring and detection of ground faults in low-voltage circuits due to the deterioration of insulation in electrical devices.
• Higher reliability ensured with improved resistance to high-frequency noise when used for inverter loads.
• Ground Fault Relays and through-type ZCTs (zero-phase current transformers) are mutually compatible.
• The through-type ZCTs are equipped with test terminals, allowing operation tests for Ground Fault Relays to be performed with ease.
