2, GB/T16917.1 applied to ac 50 hz, 50 hz or 60 hz / 60 hz and rated voltage not exceeding 440 v, rated current shall not exceed 125 a, not rated short circuit capacity of more than 25000 a, the movement function has nothing to do with the power supply voltage or with over-current protection of household and similar use of residual current circuit breaker (RCBO)

RCCB and the RCBO are called RCDS.

1. Indirect contact protection for people.

2. Provide protection for fire hazards caused by the persistent grounding fault current due to excessive current protection device (rated operation current is no more than 300mA)

3. RCD with no more than 30mA rated residual current can be used as a supplementary protection measure when other electric shock protection measures fail.

The RCBO can also be used to protect buildings and similar line equipment.
