CDB17 miniature circuit breaker is designed for overload and short circuit protections with current limited high breaking capacity, mainly applied to AC 50Hz/60Hz circuit with rated voltage 400V or less and current 63A or less.CDB17 series miniature circuit breakers are composed of moulded case, operating mechanism, contact, arc-extinguishing system, tripping mechanism, etc.

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.

This circuit breaker is designed for human indirect contact protection and over current protection in circuit of AC 50Hz, with rated voltage 230V/400V and rated up to 63A, or in similar circuits in buildings. It is also for fire protection from continuous earthing fault because of no operating of over current protection apparatus. The breaker with overvoltage protection is also designed for voltage increasing protection because of power network fault.

The circuit breaker with rated current 225A and below can be used to directly start motors. It can be separately used for infrequently changing the circuit and infrequently starting the motor in the normal conditions. 



When used in distribution, it can be used to distribute electric energy and protect the circuit and power source equipment from overload, short circuit and under voltage in the distribution network.

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.

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.

DW17 series air circuit breakers are applied to AC 50Hz circuit of rated 400V or 690V and rated current 630A-4000A to distribution electric energy. They are also used to switch circuit infrequently, or to protect the power distribution system, motor and other devices from overload, under voltage and short circuit. 



The breaker with rated current 630A or below can be used in AC 50Hz 400V network to protect motors from overload and short circuit or to start motors infrequently under normal conditions.

Residual current device (hereinafter named RCD) are designed for protection of human and animal against dangerous effects of electric current.



When parts under voltage are touched, the RCD will instantly switch off the current long before any amount or duration of current flow can cause damage. 



RCD can be applied to houses with bath tubs or shower and sauna rooms, indoor and outdoor swimming pools, farming facilities, and outdoor sockets.

CDL7 series residual current circuit breaker is designed for electric shock protection, human indirect contact protection, and electric equipment protection when human body touches electricity or electric network with leak current exceeding stipulated value. 



It is used for household or similar applications with AC 50Hz, rated working voltage 400V and below, rated current up to 63A and without relationship to line voltage. It is widely used in industry, business, and civilian household. It can be used for overload and short-circuit protections when cooperating with the CDB17 series breakers.

It is used for non-frequent making and breaking operation under normal conditions for overload and short-circuit protection. The circuit breaker with rated frame class current less than (including) 400A can be used in the squirrel cage type motor for non-frequent starting, breaking in operation. It also can provide overload, short-circuit and under-voltage protections for motors.
