General
1.Protection againstoverload and short-circuit currents
2.Protection against theeffects of sinusoidal alternating earthfaultcurrents
3.Protection against indirect contacts and additional protection against directcontacts.
4.Protection against fire hazard causedbyinsulation faults
5.Used in residentialbuilding
6.According tothe type of instantaneous release classified as follows:type B(3-5)In,type C(5-10)In

Function

1.  Personnel and fire protection

2.  Cable and line protection against overload and short-circuits.

Selection

1.  I∆n ≤ 30 mA: additional protection in the case of direct contact.

2.  I∆n ≤300 mA: preventative fire protection in the case of ground fault currents.

3.  AC class – Tripping is ensured for sinusoidal, alternating currents, whether they be quickly applied or slowly increase.

General
YCB7LE-63Y series integrated residual current operated circuit breaker is mainly used in AC50/60Hz rated voltage 230V rated current up to 63A lines,as a load line for leakage (electricshock),overload and short circuit protection.It can also be used for infrequent connection,disconnection,and switching.
