Zhejiang weharmnic Electric Co., Ltd. was established in December 2021 and is located in Qiligang Industrial Community, Liushi Town, Leqing City, Wenzhou City, Zhejiang Province. The registered capital is 10 million RMB.

Marine electrical appliances are a small branch of the low-voltage electrical industry, belonging to a niche market in China. They have long been occupied by international giants such as Schneider, ABB, Siemens, etc. This type of electrical product has long relied on imports. In recent years, China's electrical technology has made significant progress and has been able to reach the technical level of these multinational companies. In particular, with the COVID-19 raging around the world, the majority of domestic users are calling for the establishment of a domestic product supply chain to meet the new needs of the domestic shipbuilding industry. In this situation, we have established Harmonica Electric Company, which will focus on the research and development, production, and sales of marine electrical products, providing satisfactory services to domestic and international users.

The company currently has 7 full-time product R&D personnel who have been engaged in the research and production management of low-voltage electrical products for a long time. They have many patents, software copyrights, etc. in the low-voltage electrical industry and are senior engineers in the low-voltage electrical industry; The company also has a strong background as a large-scale marine electrical appliance production enterprise, and can receive strong support in marine electrical appliance technology, production, and sales.

The company has currently developed the NX6 series of products, which are small, compact, modular, high breaking, double break point, zero arc, green and environmentally friendly. They are suitable for distribution networks with AC 50Hz/60Hz rated working voltage of 690V and below, and rated current of 12.5 to 630A. They are used to distribute power and protect circuits and power equipment from overload, short circuit, and undervoltage faults, It can also be used as an infrequent start-up of the line under normal circumstances. The NX6 series circuit breaker is also equipped with an intelligent controller, which increases the selection range of setting current. It also has functions such as LCD display, overload setting current, short circuit short delay current, short circuit instantaneous current, and trip time that can be set, short circuit instantaneous three-stage protection, undervoltage protection, etc; And it has an RS485 communication interface that can be used through the MODBUS-RTU protocol; Exchange data with the outside world to achieve remote signaling, remote control, and telemetry functions. Remote signaling: indication of breaking/closing, tripping, alarm, and fault status; Remote control: breaking, closing, resetting; Telemetry: three-phase current, N-phase current, grounding current, trip memory function, and the ability to query the parameters of the last three trip records, further improving the reliability and continuity of power supply. The product complies with standards such as GB/T14048.2, GB/T2270, and IEC60947-2.

The company has currently completed the production line of this product and completed the product certification of the classification society. The company will introduce ERP management software to effectively manage the production, sales, and inventory processes of its operations. The company is committed to building a quality management system based on ISO9001, an environmental management system based on ISO14001, and an occupational health and safety management system based on ISO45001. To create a harmonious and safe working environment for employees, ensuring the stability of product quality. The company will implement institutionalized management as
