General
YCB7RL-100 series electromagnetic residual current operated circuit breaker (RCCB)  is mainlysuitable for AC distribution networks with a rated working voltage of 230V or 400V at 50Hzand a rated current of 63A.Used for indirect contact protection of people,and can also beused to prevent fire hazards caused by insulation damage to circuits and equipment,resulting in ground fault currents.

General
YCH7-125 series isolating switch is suitable in the resistive circuit of AC 50/60HZ,rated voltage 230/400V,rated current up to 125A.
It’s used primarily for circuit’s turning on or off in non-loadedsituation.And it functions on connection and isolation between lines and power,especially suitable to isolate power effectively and prevent circuit breaker from closing acidentally when maintain the circuit in order to ensure the safe operation of maintainer.
Standard:IEC600947-3

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.

1.Overload protection

2.Short circuit protection
3.Controlling
4.Used in residential building,non-residential building,energy source industry and infrastructure.
