Its neutral protection is selectable between no protection, half-setting and full setting, so the same breaker covers unprotected, half-rated or fully-rated neutral circuits; Step up to the MicroLogic 5.3 E sibling in the same frame when an integrated energy meter and ZSI are required.\u003c\/p\u003e","brand":"Schneider Electric","offers":[{"title":"Default Title","offer_id":50229670773019,"sku":"C40H42D400","price":1369.3,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0903\/7722\/4475\/files\/schneider-electric-c40h42d400.jpg?v=1790868890","url":"https:\/\/stoklink.com\/products\/schneider-electric-c40h42d400-compact-nsx400h-mccb","provider":"Stoklink","version":"1.0","type":"link"}
