FLSR100 - 100Amp Fuse

FLSR100 - 100Amp Fuse

The FLSR100 is a 100-amp Class R time-delay, current-limiting fuse designed to help you protect electrical distribution systems and industrial equipment from damaging overloads and short circuits. Featuring a knife-blade design, this non-indicating fuse is well-suited for installations where dependable overcurrent protection and high interrupting capacity are essential. With an impressive 200 kA interrupting rating at 600V AC, the FLSR100 is engineered for demanding commercial and industrial applications where minimizing equipment damage and reducing downtime are priorities. Its time-delay characteristics allow temporary inrush currents from motors, transformers, and other inductive loads to pass without unnecessary fuse operation, helping you to improve a system reliability while maintaining a high level of circuit protection. Whether you use it in motor control centers, panelboards, switchboards, or other power distribution equipment, the FLSR100 delivers consistent performance for critical electrical systems.
