FRSR6570758090100 is a 600V, 100A timedelay fuse (FRSR100) from the FRSR series. It provides dependable overcurrent protection with a time-delay to tolerate inrush, helping prevent nuisance trips while guarding connected equipment. Key benefits - Timedelay (slow-blow) operation handles startup surges in motors, transformers, and power supplies. - 600V rating and 100A current rating; part of a family that covers 65A to 100A for flexible matching. - Durable construction with high quality terminals designed for reliability in industrial panels and equipment. - Compact form factor suitable for panel mounting or inline protection in electrical assemblies. Typical applications - Motor control circuits and drives that experience startup inrush. - Transformer-fed power supplies and DC bus protection. - HVAC, refrigeration, and industrial automation panels requiring reliable protection. Why this matters - Reduces nuisance trips from inrush while maintaining solid short-circuit protection. - Supports longer equipment life and lower maintenance with predictable, standards-aligned performance.
