Detailed Residual Current Device Description
The item accords with IEC, CEE, VDE, and BS standards. To mainly
prevent electric fire and personal accident caused by personal electric
shock or leakage of electrified wire netting, this RCCB is
a current - operated, and is purely electromagnetic, fast leakage protector,
which can break off fault circuits rapidly in order to avoid accidents. This circuit with
AC 50 / 60Hz, 415V three phases and below is for
industrial and mining purposes, 240V single phase, large buildings, and commerce.
The item is precise, no auxiliary power, has fewer elements, and high
working reliability. The mutual inductor of the item is used
to test vector differential values of passing currents, and produces
a relevant output power and adds it to the tripper in secondary winding. The function of the switch won't be influenced by
ambient temperature and lightning.
If the current of vector differential value of protected circuit of
personal electric shock is up to or over leakage operating current, the
tripper will act and cut off for protection.
Our Residual Current Device comply with International Quality Standards and their quality and durability are fully guranteed.
