Its response is specified at 8 seconds at 500% of rated current, a useful number when you're checking the required fuse characteristics against equipment documentation. Eaton also lists Finger safe and 7.27W power loss among the specifications for this catalog number. For an electrician or maintenance technician, that means the important identification details are all here: amperage, voltage, fuse class, interrupting ratings, response, connection style, and dimensions.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e4A Class RK5 configuration.
