Time-Delay Protection for Motor Starting
Electric motors and transformers often generate temporary inrush current during startup. A fast-acting fuse may open during normal operation if it cannot tolerate these temporary current surges.
The Bussmann FRS-R-100 uses a dual-element time-delay design that allows temporary startup current while protecting circuits against prolonged overload conditions and short circuits.
Class RK5 Current-Limiting Protection
The FRS-R-100 is a Class RK5 fuse designed for reliable industrial circuit protection. Its current-limiting capability helps reduce the energy released during fault conditions, helping protect conductors and electrical equipment.
With a 200 kA RMS symmetrical interrupting rating at 600 Vac, the FRS-R-100 is designed for demanding industrial applications where high available fault current protection is required.
Industrial Power Protection Solution
The FRS-R series is widely used in industrial and commercial power systems where motors, transformers and other inductive loads require dependable time-delay protection.
The FRS-R-100 provides a balance between motor starting tolerance and reliable overcurrent protection, making it suitable for industrial distribution and machine power applications.
Compatible Fuse Holder Requirements
The FRS-R-100 must be installed in a properly rated Class RK fuse holder. Fuse holder selection should match the fuse voltage rating, current rating, interrupting requirements and installation environment.
Always verify the complete fuse holder specification before installation or replacement.
FRS-R-100 vs FRN-R-100
The FRS-R-100 and FRN-R-100 belong to the same Fusetron RK5 family but have different voltage ratings.
FRS-R-100 is rated for 600 Vac, while FRN-R series products are typically associated with lower voltage applications. Always confirm the exact catalog number before ordering.
Standards and Compliance
