Bussmann 170M7084 High Speed Fuse 3000A 690V 4BKN 65

The Bussmann 170M7084 is a high-speed, square-body fuse (size 4) in Eaton’s Bussmann Series designed to protect heavy-current circuits by delivering rapid fault clearing. It is rated for 3,000 A at 690 V AC with a 200 kA interrupt rating, making it suitable for large power distribution panels, motors, pumps, and other high-current loads where fast protection matters. The fuse uses flush-end connections in the 4BKN/65 configuration and measures 105 mm long by 120 mm wide by 67 mm high. It carries UL and IEC approvals and aR protection, with a type K indicator for fault signaling when the device operates. Typical applications include exterior and interior lighting, security lighting, parking-lot lighting, as well as electric motors and pumps in commercial or industrial environments requiring reliable overcurrent protection at 690 V.
