China Made Residual Current Circuit RCCB 4p 30mA 6ka, Find details about China Circuit Breaker, Miniature Circuit Breaker from China Made Residual Current Circuit RCCB 4p 30mA 6ka
Functions
Switching and isolation function.
Both Pin or Fork busbar connection.
Protection against fire hazard caused by insulation faults.
Protection against the effects of sinusoidal alternation earth fault currents.
Protection against indirect contacts and additional protection against direct contacts.
Used in residential building non-residential building energy sources, industry and infrastructure.
RCCBs are further divided into types depending on the operating function:
Type S: For selectivity, with time-relay.
Type AC: For which tripping is ensured for residual sinusoidal alternation currents, whether suddenly applied or slowly rising.
Type A :For which tripping is ensured for residual sinusoidal alternating currents and residual pulsation direct currents, whether suddenly applied or slowly or slowly rising.
Tripping sensitivity data:
RCCB with a rated residual current of maximum 30mAare used for personnel, material and fire protection, as well as for protection against direct contact.
RCCB with a rated residual current of maximum 30mA are used as preventative fire protection in case of insulation faults.
