This model is identified as a 250 A, 600 V ground fault module (GFM250Z3), a variant within the GFM250 family; Schneider Electric documentation for the GFM250 family generally lists a 40–200 A operating range, while listings for the Z3 variant commonly describe it as a 250 A unit. The unit shown is noted as missing its lug cover, a condition often encountered in secondary market listings. The GFM250 family modules are UL\/CSA listed and are designed to work with MicroLogic trip units on PowerPact H- and J-frame breakers to provide Ground-Fault Protection of Equipment (GFPE) in industrial and commercial panels, making them suitable for protecting feeders, switchgear, and other heavy‑distribution equipment in 600 V systems. \u003c\/p\u003e\u003c\/div\u003e","brand":"Square","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46259058311402,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-012.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/square-d-gfm250z3-ground-fault-module","provider":"GTG Hardware","version":"1.0","type":"link"}
