Residual Current Circuit Breaker
Series KRD1-63
Appearance
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 63A.
Tripping senitivity
30mA - additional protection agains 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 against indirect contact, as well as
fire harzard
Detectable wave form
Type AC
: For which tripping is ensured for residualsinusoidal 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.
