Double Pole White RCCB Circuit Breaker AC Type 300ma Plastic
Texture
STID-63 series residual current circuit breaker is in conformity with the
standards of IEC61008.It can cut off the fault circuit immediately
on the occasion of shock hazard or earth leakage of trunkline.Thus
it is suitable to avoid the shock hazard and fire caused by earth
leakage.It can be used in circuits up to single phase 240V,three
phase 415V,50 or 60Hz.
1.Model:
- AC type
Tripping is ensured for slowly increasing sinusoidal AC residual
currents.
- A type Tripping is ensured for sinusoidal AC residual currents
and for pulsed DC residual currents, whether applied suddenly or
increasing slowly.
- S type
Tripping is ensured not only for sinusoidal AC residual currents
but also for pulsed DC residual currents whether applied suddenly
or increasing slowly. S type with filters against spurious tripping
caused by harmonics and transient surges. With the impact of 8/20us
surge 3000A, this high immunity RCCB will still be in stable
status.
2. Tripping sensitivity
10mA - precision instrument leakage protection and bathroom use.
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/500mA - protection against indirect contacts, as well as fire
hazard.
3. Tripping time
Instantaneous - It ensures instantaneous tripping (without
time-delay).
Short time delay - It ensures any tripping at least 10ms.
Selective - It ensures total discrimination with a nonselective RCD
placed downstream.
