CDL7 series residual current circuit breaker is designed for electric shock protection, human indirect contact protection, and electric equipment protection when human body touching electricity or electric network with leak current exceeding stipulated value. It is used in household or similar applications in AC 50Hz circuit with rated working voltage 400V and below, and rated current up to 63A, without relationship to line voltage.

It is widely used in industry, business, and civilian household. It can also be used for overload and short-circuit protections cooperating with the CDB17series breakers.

CDM1 series molded case circuit breaker is suitable for the circuit of AC 50/60Hz, rated current 630A, rated operating voltage 690V or less .

The series circuit breaker, in the distribution network, can be used for distributing the energy or electricity and protecting the circuit and power device against overload, short-circuit and under-voltage.

The circuit breaker with the frame rated current 400A or less can be used for protecting motors and starting motors non-frequently. Under normal conditions, it can also be used for making and breaking circuit frequently.

CDW7 series multi-functional circuit breaker is designed for power distribution, circuit and equipment protection against such failures as overload, under-voltage, short-circuit and single-phase earthing.

They can be widely applied in the power distribution nets with AC 50Hz, rated operation voltage 400V or 690V and rated current from 400 to 6,300A. The intelligent release is designed with an excellent selective protection as the key part of the circuit breaker, to avoid power supply fault, and provide a more reliable, continuous and safer power supply system.

CDY1 series surge protective devices (SPD) are applied for the equal potential link of TT.IT.TN-STN-C-S, low-voltage power systems of AC 50/60Hz and 400V or less. They can protect the electric network from over voltage caused by thunderstroke or surge.

DZ47 circuit breakers are mainly applied to AC 50 / 60Hz circuits, with rated voltage of 230V/400V or less and rated current up to 63A.

DZ108 series circuit breakers are applied to protect motors from overload and short circuit in circuit of AC 50/60Hz, with rated working voltage to 660V and rated working current from 0.1 to 63A.
They can be used to start and break the full pressure of motor in AC-3 load and also can be used to protect the circuit and power supply from overload and short circuit in the distribution network. They conform to IEC60947-2 and IEC60947-4 standards.
