Usage: HGW1 (DW45) series intelligent universal circuit breaker, which absorbs the advantages of various domestic intelligent circuit breakers, has the characteristics of compact structure, small size, high reliability, short full breaking time, and no arcing. The equipped intelligent controller not only has multifunctional protection features, but also has various auxiliary functions such as ammeter, voltmeter, power factor meter, fault inspection, self diagnosis, MCR, etc.

At the same time, it has a communication interface that can achieve long-distance four remote functions. The product has passed the strict assessment of the latest international electromagnetic capacitance standard IEC60947-2 (97) and various types of experiments, and its main technical indicators have reached the advanced level of similar foreign products in the 1990s. To meet the requirements of low current grounding protection in direct grounding systems and grounding protection requirements in high impedance grounding systems. Added load mode leakage protection function. The unique new type of undervoltage backup device not only has the undervoltage delay protection function with adjustable action value and time, but also works as a dual backup protection for circuit breakers in conjunction with intelligent controllers, and also serves as a backup protection for line faults. At the same time, due to the use of self-priming scheme, it has anti misoperation function. When the power grid is below 85% Uc, the circuit breaker cannot be closed, and there will be no opening or closing process due to low voltage or line faults. The HGW1 series products have good technical performance, stable and reliable quality, and significant differentiation advantages. In recent years, they have been selected as the preferred products by major design institutes in various new low-voltage devices and have been widely used in many large and medium-sized key engineering projects in China. Mainly used in distribution networks for distributing electrical energy and
Protect the circuit and current equipment from the hazards of overload, undervoltage, short circuit, single-phase grounding and other faults. It has multiple intelligent protection functions, can achieve selective protection, and has accurate actions, which can avoid unnecessary power outages and improve power supply reliability.
