Overview of domestic and foreign Principal company products

1.ABB B series, A Series in early 1980s, the Shanghai people’s Electrical Appliance Factory, Beijing Electric Factory as a production license form, technology introduction of ABB B series has a preliminary modular structure; after the launch of the EB, EH series; 90’s launched the A series. A series contactor has 9 ~ 1050A22 current level, 8 kinds of models, the application of the environment temperature is: – 40, 70, is the characteristics of the contactor.
2 Fuji Corp’s SC-E series SC-E series is a joint venture between Changshu Switch Factory Co., Ltd. and Fuji Corp, there are 9 ~ 800A18 current rating, 10 kinds of models. In addition to the characteristics of the module, the volume is small, its bright spot. For example, the SC-E25 of the rated current 50A of 90mm x 54mm x 96mm, only for the same current rating of ABB A50D 50.6%, is a Schneider Inc LC1-D50 38.5%, with a high reliable contact performance (DC5V, 3mA).
3 Schneider Inc LC1-D Series in the early 1980s, Tin Shui 213 machine tool electric plant to introduce the Schneider Inc LC1-D series of contacts, is the first to enter the country of the contactor. At that time, LC1 by the current size of 9 ~ D 95A series and 115 ~ F 780A series. In recent years, the introduction of a current level of 9 ~ 620A20, 8 models of the LC1-D series. The product is a typical representative of the modular structure, further reducing the flying arc distance, improve the protection level, operating frequency can be as high as 3600 /h (small current specifications) or 2400 /h (large current specifications).
4 SIEMENS’s 3RT series SIEMENS 3RT series contactor inherited the 3TB’s life span, the coil module, easy to replace the advantages, and the realization of the full plastic and high protection (IP2x). Full range of 7 to 500A19 current rating, 7 kinds of models, the highest mechanical life of 30000000 times, the average power consumption of the coil is easy to be similar to the characteristics of the same.
5 domestic C J40, CJ45 series products of this series of products mainly by Shanghai Electrical Apparatus Research dominated development, Hangzhou Zhijiang switch factory, Shanghai People’s Electrical Appliance Factory, Tianjin Baili, Chint Electric Appliance Co., Ltd., the production of C J40, CJ45; Tianshui 213 factory introduced production gsc1 column; Shanghai Liangxin electrical appliance Co., Ltd. of the Ndc1 series, after the two basic sources in the form of LC1. CJ45 from 6.3 to 800A19 current specifications, 10 kinds of models, the mechanical and electrical life of 10000000 times and 1000000 times, with a modular and fully plastic structure, there is a delay, coil surge suppression, mechanical interlocking and other accessories, in particular, the use of Ag-Ni (16A and below) or AgSnO2 (16A above), with environmental protection.
