Abstract
A circuit breaker includes a coil arrangement for actuating an armature to open the breaker. To prevent false tripping during high transient currents drawn by a load, the coil arrangement has first and second coils, electrically connected in series. The second coil is interposed between the first coil and the armature and is wound in an opposite direction from the first coil to produce an opposing field.
