Abstract: Direct current, which was one of the main means of distributing electric power, is still widespread today in the electrical plants supplying particular industrial applications. The advantages in terms of settings, offered by the applicants of d.c. motors and by supply through a single line, make direct current supply a good solution for railway and underground systems, trams, lifts and other transport means. The paper presents the calculation of the magnetic field in the arcing chamber of the current-limiting circuit breaker of the direct current 1250 A, 750 V. Current-limiting circuit breakers play an important role in electrical low-voltage circuits. Due to the high short-circuit currents it is necessary a very short time to switch off the defective branch. For this the current limiting circuit breakers are conceived as elaborated solutions especially for the arc quenching system, meaning the path of current and the arcing chamber. In this paper the authors pres!
ent few optimization solutions of some quenching systems which will lead to more performing constructive choices. The finite element software package ANSYS is use for calculation of the magnetic field components.
