General
1.Protection against overload and short-circuit currents
2.Protection against the effects ofsinusoidal alternating earthfault currents
3.Protection against indirectcontacts and additional protection against direct contacts.
4.Protection against fire hazard caused by insulation faults
5.Used in residential building
6.According tothe type of instantaneous release classified as follows:type B(3-5)In,type C(5-10)In,type D(10-20)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.

Voltage and current display relay is a microprocessor-based voltage monitoring device for single-phaseAC networks toprotect electrical equipment from surgevoltage.The device analyzes themain voltage and displays itscurrent value on a digitalindicator Load isswitched by electromagnetic relay.The usercan set the currentvoltage value and delay timethroughthe button.The value is stored in non-volatile memory.Aluminum wires and copperwires can beused for connection.
General
Function description:When a phase of L1,L2,L3 overvoltaged,undervoltaged orphase lacked,the relay will be disconnected and automatically search for the normalphase,and switch to open the relay of the normal phase,switching priority
L1>L2>L3!

General
YCCH6Z series AC contactor (hereinafter referred to as the household
appliances control a contactor) is used for remote switch on and off without a
sense of feeling or low load, resistance furnace, household appliances and similar low load, motor and other household.
The main contactor is used in AC 50Hz/60Hz, rated voltage to 400V, rated current
of power system to 100A, AC-1, AC-7a (in no sense or sense of low load,
resistance furnace, household appliances and similar low load) categories, long distance switch and control circuit.
Contactor is not used for breaking short circuit current, so it is necessary to choose suitable short circuit protection electrical equipment.
