FRSR6570758090100 — FRSR100 timedelay fuse, 600 V, 100 A (FRSR series) What it does Provides dependable overcurrent protection with a time-delay (slow-blow) characteristic that tolerates start-up and inrush currents while clearing sustained overloads and short circuits. Fits applications requiring a 600 V voltage rating and 100 A current rating; part of the FRSR series family that covers 65 A to 100 A for easy capacity matching. Key benefits — why you need it Prevents nuisance trips: the timedelay element lets motors, transformers, and power supplies draw short-duration inrush without opening, reducing unnecessary downtime. Protects equipment and wiring: clears true overloads and short circuits to limit damage to connected components. Reliable connections: durable construction and high-quality terminals designed for heavy-duty use in industrial panels and equipment. Flexible installation: compact form factor supports panel mounting or inline protection in electrical assemblies, saving space in control cabinets. Important attributes Function: time-delay (slow-blow) fuse for overcurrent protection with inrush tolerance. Compatibility: part of the FRSR series (FRSR100 model), interoperable with systems designed for cartridge-style fuses in the 65 A–100 A range. Size and mounting: compact cartridge style suitable for panel-mount or inline arrangements. Build and performance: robust construction and quality terminals for consistent, predictable protection; standards-aligned performance for industrial use. Practical use scenarios Motor starter protection: installed on motor control circuits or drives to permit startup surges while protecting against sustained overload or faults. Transformer-fed power supplies and DC bus protection: prevents nuisance fuse operation from inrush during transformer energization while safeguarding downstream electronics. HVAC and refrigeration panels: protects compressors and control equipment subject to frequent start/stop cycles without generating false trips.
