Mersen Ferraz Shawmut ATQR Series Time Delay Class CC Fuses - Multi Amp Lot (1/4A to 15A, 600VAC)

This multi-box lot consists of various Mersen (formerly Ferraz Shawmut) ATQR series time-delay Class CC fuses, designed for superior protection in control circuits, lighting, and small motor applications. The lot includes fuses with ampere ratings such as ATQR1/4, ATQR1, ATQR2, ATQR5, ATQR10, and ATQR15, all rated for 600VAC/300VDC. These fuses offer time-delay characteristics to handle inrush currents from motors and transformers, while providing current-limiting protection to minimize damage from short circuits. Key benefits include a high interrupting rating of 200kA AC, rejection features to prevent incorrect fuse installation, and compact size for space-constrained panels. Compared to standard fast-acting fuses, ATQR models provide better tolerance for temporary overloads without nuisance tripping, making them ideal for industrial and commercial electrical systems. Drawbacks may include higher cost per unit versus basic fuses and the need for compatible Class CC holders. The fuses in this lot appear new or unused, stored in original packaging, with some boxes opened. Applications span branch circuit protection, control panels, and HVAC systems. For detailed specs, refer to Mersen's Amp-Trap 2000 datasheet. Estimated total quantity: approximately 50 fuses across multiple ratings, based on image analysis.
