Abstract:

The terminal temperature rise of miniature circuit breaker is not only the main performance in product development and design,but also an important parameter for fire prevention,which has an important impact on the actual use of products.Among them,the current size,wire type and specification,structure design of wiring frame,tightening torque and so on are important factors affecting the temperature rise of terminal.This paper mainly compares the terminal temperature rise under different influence factors through experiments,and obtains some important conclusions.

Key words: miniature circuit breaker, type and specification of conductor, structure design of terminal block, tightening torque
