Eaton Bussmann series LPS-RK fuse – Low-Peak RK1 Time-Delay Fuse The Eaton Bussmann series LPS-RK fuse is a Class RK1 dual element, current-limiting, time-delay fuse designed for low voltage applications up to 600 Vac and 300 Vdc. It provides ultimate protection for feeder and branch circuits, motors, transformers, solenoids, and general purpose circuits. This fuse is suitable for electrical distributors and switchgear suppliers requiring reliable overcurrent protection with high interrupting ratings and time-delay performance. Specifications Amperage: 50 amperes Voltage Rating: 600 Vac / 300 Vdc Interrupt Rating: 100 kiloamps DC, 300 kiloamps AC RMS Sym. Fuse Class: Class RK1 Connection Type: Ferrule end x ferrule end Dimensions (L x W x H): 5.5 in x 1.06 in x 1.06 in Time-Delay: 10 seconds minimum at 500% of rated current Catalog Number: LPS-RK-50SP Product Weight: 2.6 lbs Non-indicating fuse type UL Listed and CSA Certified (UL 248-12, CSA C22.2 No. 248.12) Features Dual-element design provides fast short-circuit protection with time-delay for temporary overloads Current-limiting capability reduces damaging thermal and magnetic effects downstream High interrupting rating (300 kA at 600 V AC, 100 kA at 300 V DC) allows safe installation in virtually any application Consistent 2:1 ampacity ratios simplify selective coordination Time-delay permits 130% full load amperage sizing for motor backup protection Reduces fuse inventory by up to 33% when upgrading to Low-Peak fuses Protects against single-phase motor damage and supports “no damage” Type 2 coordinated protection for NEMA and IEC motor controllers Downloads & Links Spec Sheet Spec Sheet
