Summary:A contactor assembly includes a stationary contact, an arc contact, an arc arrestor, and a magnetic intensifier. The magnetic intensifier is constructed to be secured in generally close proximity to the stationary contact. During communication of power through the contactor assembly, the magnetic intensifier accentuates a magnetic field associated with the stationary contact and increases the magnitude of a magnetic force directed to the arc arrestor. A pair of arc guides extend along the magnetic intensifier and, cooperatively with the magnetic force, ensure efficient, repeatable, and expedient transfer of a circuit termination arc to the arc arrestor. Such a construction increases the operable range and lifecycle of the contactor by reducing the damage associated with propagation of the circuit termination arc.
