Application:

• The moulded case circuit breaker is mainly used in distribution network of AC50Hz or 60Hz, rated voltage up to 690V, rated working current up to 1600A to distribute electric power and to protect the line and the equipment from being damaged due to overload .short circuit and under-voltage.

• lt can also be used for unfrequent motor start and for motor overload,short circuit and under voltage protections

• Standard: I EC 60947-2.

Accessories:

1. The internal annex of circuit breaker

2. Under-voltage release

3. They are 3 types of under-voltage release

1. Type: AC50Hz 110V 230V 400V ; DC 110V 220V

2. Type :AC50Hz 400V (3 phase protection that is open-phase protection)

3. Type: AC50Hz 230V , 400V .

1.3 Arm contact

1.4 Auxiliary contacts

1.4.1 Auxiliary contact ,rated current of warning contact

1.4.2 Power performance and the corresponding test conditions of auxiliary contacts

1.4.3 Auxiliary contact in the non-normal conditions connected and the breaking capacity

Note: the above two table

1. 6Pe=T0.95 empirical formula, Pe use'W' for the units, T0.95 in milliseconds

2. When the circuit breaker performance is less than the total number of 6050 times, while the aux-iliary contact's power performance times is equal to the total breaking performance times.

3. Operating frequency and the power time are allowed to with the line of main circuit breaker.

With its core brand of “Shanghai People Electric Co.,Ltd", Shangmin Electric Groupowns Low Voltage Branch, High Voltage Branch, Transformer Branch, Switchgears Branch, Sino-Deutsch DCH Energy Technology Co., LTD and three large production bases in Yueqing, Lishui and Jiangsu. It is specialized in the development, research, production and operation of high or low voltage transmission and distribution equipment, high or low voltage components and wind - solar electricity equipment. The group also involves in real estate and tourism investments and goods import and export business. 
    The group has been insisting on principles of “Quality First and Focusing on Customers”. It has established and implemented ISO9001 quality management system and applied modern enterprise management mode in a scientific manner. It has realized the scientific design of products to provide cost-effective high-quality products and services. 
  Meanwhile, driven by the innovative spirits of “Infinite possibilities and infinite pursuits”, the group has established a long-term development strategy: further adjusting industrial structure with the orientation of manufacturing high or low voltage switchgears; strengthening and improving the ability of independent production of components and extending the industrial chain, to providevariousfields with 12KV to 40.5KV high voltage switchgears, high or low voltage cabinet type substation, power transformers, as well as high or low voltage electric components. The products of the group are widely used in national key projects, especially in industrial and mining enterprises, as well as electric power transmission and distribution projects. In the biddings of National Grid and Inner Mongolia Grid in 2012, the group has made great successes owing to its excellent brand, reliable quality and reasonable price. The group has been honored “Good Faith Enterprise of Zhejiang Province”, “China Famous Brand”,  “Top 500 Enterprise in China”, “Top Ten Switchgear Enterprise in China”, “Recommended products by Sinopec and China Engineering Recommendations Association ”.The group has made an important contribution to the renovation and upgrade of rural grid and urban grade. 
    To respond positively to the new energy development strategy of China by saving energy and reducing pollution, developing and using solar energy and wind energy, the group has developed strategic emerging industries with its own advantages. Since 2008, the group has invested a lot of specialized research and development funds, manpower and materials resources in developing green lighting and using green energy. By virtue of first-class technology innovation, complete supporting facilities, and excellent system design capacities, the group has innovated solar-wind complementing street lighting system which combines the solar energy with wind energy. Natural resources are fully used to realize self-sufficiency of street lighting energy.
