Deskripsi Produk
TRIP CHARACTERISTICS
FAULT CURRENT SENSITIVITY
The RCD employs the current balance principle which involves
the supply conductors to the load (phase and neutral) wound onto
a common transformer core to form the primary windings. Under
healthy conditions, the current in the phase conductor is equal to
the current in the neutral and the vector sum of the current is zero.
RESIDUAL TRIPPING CURRENTS
Semi-conductor devices are extensively integrated in equipments in industries, commerce and in our homes.
They can be found in control panels to computers to toys.
As equipments are fed from the mains electrical supply; in the event of an earth fault, the presence of semi-conductors may result in the
normal AC waveform being replaced by a non-sinusoidal fault current. In some cases, the waveform may be rectified. These waveforms are
said to contain a pulsating DC component which can either partially desensitize a standard type AC RCD.
International standards IEC 1008 (RCCBs)

Type AC
RCDs for which tripping is ensured for residual sinusoidal alternating currents; whether suddenly applied or
slowly arising.

In the event of an earth fault, an amount of current will flow to earth,
creating an out of balance situation in the transformer assembly.
This out of balance detected by the secondary winding of the
transformer will activate the trip mechanism at a pre-determined
level. Single phase and neutral or three phases and neutral units
(suitable for both 3 wire and 4 wire systems) are available, the latter
being suitable for balanced or unbalanced 3 phase loads.
The RCD tripping mechanism will operate at a residual current of
between 50%-100% of its rated tripping current. (Sensitivity)

30mA Tripping current to provide additional protection against direct contact shock
100mA Suitable for use against direct contact shock or where protection is guard against fire hazards etc.
300mA Suitable for use in large installations where equipment protection are main considerations and
high levels of earth leakage are experienced.
