Scope of Application
• DZ47NLY-63 Residual Current operated Circuit-Breakers are suitable for AC 50Hz circuits with rated voltages up to 230V, rated currents up to 63A, and grounded neutral points. They provide protection against electric shock, overcurrent for building circuits/equipment, and fire hazards caused by ground fault currents from insulation failures.
• Supports accessories: auxiliary contacts, alarm contacts, shunt releases, under-voltage releases, over-voltage releases, under/over-voltage releases.
• Complies with
IEC 61009-1 and
GB/T 16917.1
"Residual current operated circuit-breakers with integral overcurrent protection for household and similar uses (RCBOs) – Part 1: General rules".
