Application scope Protection against the effects of earth leakage overload and short circuit currents. 2P switching of ph&N,Phase only protected against overloads and short circuits. In commercial,industrial and domestic electrical distribution systems. Note:must mot be used as the sole means of providing protection against direct contact. The RCBO incorporates a residual current operated electromagnetic release which operates without any auxiliary source of suppl to open a circuit automatically in the case of an earth leakage fault between phase and earth greater than or equal to In.The RCBO combined MCB&RCCB provides: Protection against indirect contact Complementary protection against direct contact Protection for the installation against in sulation faults Standard GB16917 IEC61009 Main technical parameters Type JVL11-32 Number of poles 1P+N Rated Current(In) 1,2,3,4,6,10,16,20,25,32A Rated operating current( I△n) 15,30,100,300mA Rated Voltage(Un) AC 230(240) V Residual operating current scope 0.5I△n~I△n Residual current off-time ≤0.3s Type A,AC Ultimate short-circuit breaking capacity(Icn) 10000A(10KA) Endurance ≥4000 Terminal protection IP20
