PA66 300ma AC Type Double Pole RCCB Circuit Breaker

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.
