Personnel and fire protection
Cable and line protection against overload and short-circuits.
I∆n ≤ 30 mA: additional protection
In the case of direct contact.
I∆n ≤ 300 mA: preventative fire protection
In the case of ground fault currents.
AC class – Tripping is ensured for sinusoidal,
Alternating currents, whether they be quickly applied or slowly increase.
1.3 Performance & Usage
Circuit breaker is mainly suitable for overload and short protection. It is especially used for illumination and distribution. It is of pleasing out-look, light weight, reliable performance, high breaking capacity, quick trip. etc.
