Abstract: An electrical switching apparatus includes a plurality of poles each comprising separable contacts, an operating mechanism structured to open and close the separable contacts and to trip open the separable contacts in response to a fault condition, and a housing enclosing the separable contacts. The housing includes an interior, an exterior, and a plurality of receptacles extending from the exterior toward the interior. A surge protection assembly includes a plurality of modules, wherein each of the modules is removably disposed in a corresponding one of the receptacles of the housing. Each of the modules provides independent surge protection for a corresponding one of the poles of the electrical switching apparatus.
