CHINT 2P 63A ELCB / RCCB (NL1-63) - 30MA , 100MA , 300MA General : ~ - Function : *Control electric circuits. *Protect people against indirect contacts and additional protection against direct contacts. *Protect installations against fire hazard due to insulation faults. *Residual current circuit breakers are used in housing, tertiary sector and industry. -Selection : Detectable wave form AC class *Tripping is ensured for slowly increasing sinusoidal AC residual currents. A class *Tripping is ensured for sinusoidal AC residual currents and for pulsed DC residual currents, whether applied suddenly or increasing slowly. S, G/SI class *Tripping is ensured not only for sinusoidal AC residual currents but also for pulsed DC residual currents whether applied suddenly or increasing slowly. *S, G/SI type with filters against spurious tripping caused by harmonics and transient surges. *With the impact of 8/20us surge 3000A, this high immunity RCCB will still be in stable status. Tripping sensitivity *10mA - precision instrument leakage protection and bathroom use. *30mA - additional protection against direct contact. *100mA - co-ordinated with the earth system according to the formula IΔn ＜50/R, to provide protection against indirect contacts; *300mA/500mA - protection against indirect contacts, as well as fire hazard.
