The breaker is mainly used in distribution network of AC 50Hz/60Hz,rated voltage up to 690V, rated working current up to 1250A to distribute electric power and to protect the line and equipment from being damaged due to overload, short circuit and under-voltage. Lt can also be used for infrequent motor start and for motor overload, short circuit and under-voltage protections.

DZ47-63(C45N) series circuit breaker is used in lighting distribution system or motor distribution system. The product is neoteric in structure, light in weight, reliable and excellent in performance. Its frame and parts adopt plastics of high fire-resistant and shockproof. The product, with long life, is mainly used in AC 50HZ/60HZ single-pole 240V or two, three, four pole 415V circuit for overload and short-circuit protection as well as for Infrequent on-and-off switching electric equipment and lighting circuit in normal case.

DZ47-100(NC100N)high breaking capacity circuit breaker is used for AC 50Hz or 60Hz, single pole 240V, 2, 3, 4, poles 415V, for protecting the circuit which overload and short circuit may take place. Lt can be used in lighting and electric motor distribution system. Meantime it is applicable to an infrequent switch the electric apparatus and lighting circuit under normal condition. Breaking capacity is up to standard of IEC947-7 10KA.

DZ47LE (C45LE) earth leakage circuit breaker is used for the protection, against electrical leakage in the circuit of 50Hz or 60Hz, rated voltage singe-phase 240V, 3 phase 415V, rated current up to 60A.When some body gets an electric shock or the residual current of the circuit exceeds the fixed value, the ELCB can cut off the power within the time of 0.1s automatically to protect the personal safety and preventing the equipment from the fault resulted by the residual current. With this function, the ELCB can protect the circuit against overload and short circuit or can be used for the unfrequent switchover of the circuit under normal conditions. lt conforms to IEC1009 standard.

The breaker is mainly suited for distribution network of AC 50/60HZ, rated working current up to 6300A, rated voltage up to 690V to distribute power and protect the line and the equipment against the damage due to overload, short circuit, under-voltage and single phase earthing in transformer's neutral point TN distribution system, lt is also used to unfrequently covert the line under normal condition. The breaker can realize selective protection which can improve the reliability of power supply and avoid unnecessary power failure.

YZW15(DW15)series universal auto air circuit breakers(herein after referred to as the breakers)are suitably used in AC 50Hz,rated current up to 4000A and rated working voltage up to 1140V(using frame level rated current 630A and below)and 380V (using frame level rated current 1000A and over)power distributing systems for power distribution and protection fo power supply circuit and power apparatus from overload, under voltage and short circuit.

This series air circuit breakers are suitable used in AC50/60Hz, 380V distributing systems with normal current up to 4000A for power distribution and overload, under-voltage and short-circuit protection of apparatus and circuit.Under normal conditions the breakers are used for infrequent switchover of circuits. The breakers with rated current below 1 250A used in 50/60Hz, 380V systems can protect motors form overload and short circuit, and actuate motors unfrequently under normal conditions.
