Abstract
A contactor assembly is adapted for switching power to a circuit having a power source. The contactor assembly includes a housing, carry contacts, and arc contacts. The housing defines an interior compartment and includes internal chamber walls that laterally extend within the compartment to define a protection chamber. The carry contacts are disposed in the protection chamber of the housing. The carry contacts include conductive bodies that protrude from the housing and are configured to close the circuit. The arc contacts are disposed in the housing outside of the protection chamber. The arc contacts include conductive bodies that protrude from the housing and are configured to close the circuit. The internal chamber walls of the housing prevent material that is expelled from one or more of the arc contacts when an electric arc emanates from one or more of the arc contacts from contaminating one or more of the carry contacts.
