Welcome to contact us for further information about our new product types of rccb or our company. It is proved by practices that types of rccb has the characteristics of .
1.1Function
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.
1.2Selection
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.
Tripping sensitivity
30mA - additional protection against direct contact.
100mA - co-ordinated with the earth system according to the formula lan <50/R,to provide protection against indirect contacts;
300mA - protection against indirect contacts,as well as fire harzard.
Tripping time
Instantaneous
It ensures instantaneous tripping (without time -delay).
Short time delay
lt ensures any tripping at least 10ms.
Selective
lt ensures total discrimination with a nonselective RCD placed downstream.
Dvolt is found with joint venture company, which have more than 20 years experience in the field. Now mainly produce Circuit Breaker, Contactor, Changeover Switch and so on.
