Product Description

Description:
· Type B RCCB is the secret that makes Electric Vehicle Charging Point much safer than traditional charging point. It is a multiple purpose safety device that manage all potential residual current, and protect users from potential electric shock.
· AC residual current.
· Pulsating DC residual current.
· Sinusoidal half-wave current superposes 6mA smooth DC residual current.
· Multifrequency recombination residual current.
· Less than 1000Hz AC residual current.
· AC current superimposes 10mA or 0.4In smooth DC residual current.
· Sinusoidal half-wave current superposes 10mA or 0.4In smooth DC residual current.
· DC residual current generated by a Single-phase rectifier circuit.
· DC residual current produced by three-phase rectifier circuit.
· Smooth DC residual current.
· 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.

Detectable wave form:
· Type B
Tripping is ensured for sinusoidal AC residual currents pulsed DC residual currents, alternating residual sinusoidal currents up to 1000Hz, pulsating direct residual currents and for smooth direct 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 IΔn<50/R, to provide protection against indirect contacts.
300mA - protection against indirect contacts, as well as fire hazard.
· Tripping time
Instantaneous
It ensures instantaneous tripping (without time-delay).
