4 Pole Rcbo Circuit Breaker MCB + RCD AC or A Type Residual Current Operated Circuit Breaker
STRO7-63 series high breaking capacity Residual current Circuit Breaker with over current protection is used in AC50/60Hz, rated voltage of 230V
2, 4 poles 400V, rated current to 63A for overload and short-circuit protection and Leakage current protection as well as for unfrequented switching under normal case.It is used extensively for industry, commercial and household.This product conform to IEC61009 standard.
General
1. Application:For protecting cables and equipments against overload and short circuit.
2. General rules for choosing RCBO
The earthing systems,short-circuit current at the circuit breaker installation point,which must always be less than the breaking capacity of this device,network normal voltage.
B curve (3-5In) protection and control of the circuits against length cables in TN and IT systems.
C curve (5-10In) protection and control of the circuits against overloads and short-circuits; protection for resistive and inductive loads with low inrush current.
D curve (10-14In) protection and control of the circuits against overloads and short-circuits; protection for circuits which supply loads with high inrush current at the circuit closing (LV/LV transformers,breakdown lamps.)
