FIELD: electricity.SUBSTANCE: circuit breaker is designed to pass and interrupt current in the main circuit. The circuit breaker includes an arc-suppression device with an arc-suppression facility, a magnetising coil (11) and a group of electrode facilities (9, 10) coupled electrically to the magnetisng coil (11). Fixed (5) and movable (6) contact elements in the first position are interconnected so that they can pass current in the main circuit. The contact element (6) is transferred into the second position remote from the contact element (5) with current interruption in the main circuit and shift of an occurring arc (17) to the arc-suppression facility. The group of electrode facilities (9, 10) is designed to interact with the arc (17) with the creation of excitation current by arcing in the coil (11). The arc-suppression facility includes a group of magnets (15, 16) creating a magnetic field (B, B) oriented radially to the arc and a force (F, F,) that shifts the arc (17) for the purpose of the arc (17) interaction with the group of electrode facilities (9, 10).EFFECT: developing the circuit breaker capable to interrupt rather low current in any direction.8 cl, 11 dwg |
