WCED 4-pole 10kA MCB 6-63A B/C/D Curve - WKC

Application
WKC range circuit-breakers are used in domestic installation, as well as in commercial and industry electrical distribution systems.

Function

• Protection of circuits against short-circuit currents; 
• Protection of circuits against overload currents;
• Switch;
• Isolation

Selection

Technical data of the network at the point considered: the earthing systems (TNS, TNC), short-circuit current at the circuit-breaker installation point,which must always be
less than the breaking capacity of this device, network normal voltage.

Tripping curves:
B curve (3-5In)---protection for people and big length cables in TN and IT systems.
C curve (5-10In)---protection for resistive and inductive loads with low inrush current
D curve(10-14In)---protection for circuits which supply loads with high inrush current at the circuit closing (LV/LV transformers, breakdown lamps)

Please choose your curve and amperage from the options below

2-pole, 3-pole and 4-pole options also available:
