Scope of Application
• DZ47LEK-63 series Residual Current operated Circuit-Breakers are suitable for AC 50Hz circuits with rated voltages up to 400V and rated currents up to 63A. They provide household and similar applications with earth leakage and overload protection to prevent fires or casualties caused by circuit leakage or electric shock. They also offer overvoltage protection against excessive voltage rises due to grid faults.
• Specialized Models: 1P+N and 2P configurations can be custom-produced with overvoltage protection. Beyond standard overload/short-circuit/leakage protection, these safeguard against voltage surges (e.g., from neutral line miswiring, disconnection, or three-phase imbalance).
• Complies with
IEC 61009-1 and
GB/T 16917.1
"Household and similar uses – Residual current operated circuit-breakers with integral overcurrent protection (ICBO) – Part 1: General rules".
