Electrical switching apparatus accessory sub-assembly employing reversible coil frame, and accessory and electrical switching apparatus employing the same

An electrical switching apparatus comprising:

• separable contacts;
• an operating mechanism structured to open and close said separable contacts;
• a trip mechanism structured to trip open said separable contacts, said trip mechanism including a trip bar;
• an enclosure enclosing said separable contacts;
• and
• an electrical switching apparatus accessory comprising:
• an accessory sub-assembly comprising:
• a coil frame including a first end and a second end opposite said first end,
• a housing including a plurality of interior surfaces, a first end and a second end opposite the first end of said housing, the second end of said housing having an opening,
• wherein a number of the interior surfaces of said housing are structured to selectively hold said coil frame in either one of a first position in which the first end of said coil frame faces the first end of said housing and the second end of said coil frame faces the second end of said housing, and a second position in which the first end of said coil frame faces the second end of said housing and the second end of said coil frame faces the first end of said housing,
• a coil assembly comprising a conduit, a number of coils within said coil frame and being disposed on said conduit, a ferrous plunger movable in said conduit, and a stem coupled to said ferrous plunger,
• a first ferrous member disposed proximate the first end of said coil frame,
• a second ferrous member having an opening and being disposed proximate the second end of said coil frame, and
• a circuit structured to energize at least one of said number of coils,
• wherein said stem is structured to pass through the opening of said housing, and
• wherein said stem is structured to engage said trip bar to trip open said separable contacts.
