Abstract
A magnetic module in a circuit interrupting system is configured to generate a blow-on force that pushes a moving contact toward a stationary contact. The magnetic module includes: a coil conductor having an opening through which a moving stem of the moving contact may move, wherein the coil conductor is electrically connected to the moving stem and a first auxiliary conductor, wherein the coil conductor is configured to allow current to flow from the moving stem to the first auxiliary conductor; a plunger attached to an end of the moving stem; and a first magnetic core shaped to fit around a first section of the coil conductor, wherein the first magnetic core is configured, when current flows through the coil conductor to the first auxiliary conductor, to become magnetized, attract the plunger toward the magnetic core, and cause the moving stem of the moving contact to move toward the stationary contact.
