| Abstract | A novel multifunction integrated low voltage apparatus is presented in this paper. Although its appearance looks a contactor, its contact and arcing chamber is innovated and power electronic technology is tied with its electromagnetic system so as to improve effectively the apparatus's making and breaking current capability, furthermore, microcontroller is imbedded in the apparatus as its measure and control core. As a result, it is provided with several apparatus's functions including contractor, circuit breaker, thermal relay and so on. The static characteristics and dynamical characteristics of the electromagnetic system is computed and analyzed based on finite element method by means of the ANASY software in this paper, the influence of counterforce, coil diameter and number of windings for the breaking velocity and resetting time during switch-off is studied. And the prototypes have been tested and put to use, the results show a good agreement with the predictions. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
