The YCB7-63N series miniature circuit breaker are suitable for overcurrent protection building line facilities and similar purposes in AC 50/60Hz, rated voltage 230V/400V,
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.
General

The intelligent remote controlswitchis suitable for users orloads with AC50Hz/60Hzratedoperating voltage of 230V,and ratedworking current of63Aand below.It hasabeautiful appearance,excellent performance,and reliable operation.It canquicklyswitchon/off and is installedwith modularrail It is mainlyused inhomes,shopping malls,office buildings,hotelsschools,hospitals,villas,andotherplaces.
Voltage and current display relay is a microprocessor-based voltage monitoring device for sinale-phase AC networks to protect electrical equipment from surge voltage. The device analyzes the main voltage and displays its curent value on a digital indicator. Load is switched by electromagnetic relay. The user can set the current voltage value and delay time through the button.The value is stored in non-volatile memory. Aluminum wires and copper wires can be used for connection.
