Description
The Mersen CC TD Fuse 600V 1-1/4A ATQR (ATQR1-1/4) is a time-delay fuse specifically designed to handle the high inrush currents common in control transformers, solenoids, and other inductive loads. Part of the Amp-Trap 2000 series, this fuse offers robust protection for branch circuits in electrical distribution systems, ensuring optimal performance and reducing the likelihood of nuisance tripping.
Key Features
- Time-Delay Capability: Designed to accommodate the high inrush currents from control transformers and solenoids, preventing unnecessary fuse operation.
- Highly Current-Limiting: Effectively reduces peak let-thru current, protecting downstream equipment from damage.
- Rejection-Style Design: Prevents improper fuse replacements when used with the appropriate fuse blocks, ensuring the correct installation.
- High-Visibility Label: The bright orange label facilitates easy identification and quick replacement.
- Durable Construction: Features a fiberglass body that maintains its dimensional stability in harsh industrial conditions; metal-embossed date and catalog number ensure long-lasting traceability.
- Efficient Arc Quenching: Contains high-grade silica filler that provides rapid arc quenching and excellent current-limiting performance.
