They \u003cbr\u003e  have moderate current limitation.","brand":"Edison Fuse","offers":[{"title":"Default Title","offer_id":42862872789081,"sku":"EDF-ECNR400","price":0.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0601\/1171\/6441\/files\/ECNR400_1_20-_208272dd02-0b26-4948-ba7b-dbd8ad857fcb.jpg?v=1764013437","url":"https:\/\/www.guillevin.com\/products\/fuse-class-rk5-time-delay-400a-250v-edf-ecnr400","provider":"Guillevin","version":"1.0","type":"link"}
