Abstract

The circuit-breaker has a main circuit including a contact zone provided with a main contact bridge (5) cooperating with fixed contacts (4, 6), and a current limiting resistor (10) limiting current in a secondary circuit. The secondary circuit has a movable contact (11) opened by a single unlocking latch that cooperates with the bridge and with the movable contact. The bridge and the movable contact are mechanically connected to a common contact holder (13), with independent relative movement, and are arranged electrically independent from one another.
