48-mm Ground Fault Relay for Low
Voltages
• 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-fre-
quency noise when used for inverter loads.
• Remote monitoring of cubicles is possible with automatic-reset
models.
• Ground Fault Relays and through-type ZCTs (zero-phase cur-
rent transformers) are mutually compatible.
• The through-type ZCTs are equipped with test terminals, allow-
ing operation tests for Ground Fault Relays to be performed with
ease.
• Series now includes K6EL-R50, which operates at
50 mA
