Bussmann series Low-Peak 600 V LPS Class RK1 time-delay fuses, 70-600 A data sheet no. 1002
Time-delay, dual-element design delivers motor-friendly inrush tolerance while maintaining fast fault interruption. This reduces nuisance trips and extends equipment life, making it ideal for motor drives, pumps, and conveyors in continuous-process environments. High interruption ratings provide safe clearance of short circuits without damaging upstream equipment, translating to improved panel reliability and lower maintenance costs in high-energy feeders and distribution panels. CE Marked compliance and Class RK1 coordination help engineers meet regulatory requirements while ensuring selective protection in European and global installations. Blade-end x blade-end connections simplify retrofits in standard Bussmann series enclosures, while electrically isolated end caps enhance servicing safety and minimize the risk of accidental contact during maintenance. The device’s standard packaging and 13.38 in length with a 5.6 lb weight support straightforward stocking and quick replacements in busy electrical rooms.
