DIN 48 × 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 K3HB-VLC-CPEC21 AC/DC24 PDF datasheet K3HB-VLC-CPEC21 AC/DC24
Higher reliability ensured with improved resistance to high-fre,
quency 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 withease K3HB-VLC-CPEC21 AC/DC24 PDF datasheet . Detect abnormal voltages applies to equipment to,
protect against equipment failure.
