Abstract (en)
[origin: EP0515292A1] The invention relates to an electromagnetic trip (24) for a low-current, in particular less than a few amperes, miniature circuit breaker. To avoid a magnetic leakage field around the trip, the yoke (60) includes a first ferromagnetic piece (62) serving as means of support to the coil (50) and cores (48,54) assembly, and a second ferromagnetic piece (64) assembled to the first of conjugate shape to form a complete screening member. Magnetic saturation of the electromagnetic is then retarded when a short-circuit current is detected. <IMAGE>
