Residual Current Circuit Breaker
Series KRD2-100
Appearance
Combination of auxiliary element
Combination of Auto recloser
Characteristic
Protection against indirect contacts and additional
protection against ditect contacts
Protection against fire hazard due to insulation faults.
Contact position indicators: easy to recognize
contact status,
Position O: Indicator Green, Breaker is OFF
Position I: Indicator Green, Breaker is On
Magnetic type with the advantage of Voltage
independent function,
Nonzero Voltage is only necessary when
testing of the RCCB with the T test button,
Be tested regularly with a period of one month,
Easy wiring and mounting,
The current is up to 100A.
Combination with auxiliary
Combination with Auto-recloser
Characteristics for RCCB Type B
Protection in the event of a continuous fault current
on three phase net works generated by:
Controllers and variable speed drives
Battery chargers and inverters
Backed-up power supplies
Protection against fault currents:
Sinusoidal AC residual currents (AC type)
Pulsed DC residual currents(A type)
Subject to the standard IEC61008+IEC62423
Tripping senitivity
30mA - Protection of persons against electric shock
by direct contact;
100mA - Co-ordinated with the earth system according
to the formula I∆n<50/R, to provide protection against
indirect contacts.
>=300mA - Protection of persons against electric shock
by indirect contact
300mA or 500mA - protection of installations against
the risk of fire
Detectable wave form
Type AC
: For which tripping is ensured for residual
sinusoidal alternating currents, whether suddenly
applied or slowly rising.
Type A 
: For which tripping is ensured for residual
sinusoidal alternating currents and residual pulsating
direct currents, whether suddenly applied or slowly
rising.
Type S
: For selectivity, with time delay.
Type S : For selectivity, with time delay.
Type B
: For normal AC, but also high frequency
AC and smooth DC residual currents
