Description
The Mersen ATQR25 is a Class CC Time-Delay Fuse designed for protection in circuits with high inrush currents, such as those found in control transformers and solenoids. It provides reliable and efficient circuit protection for electrical distribution systems.
Key Features
- Time-Delay Characteristic: Specifically engineered to handle the high inrush currents associated with control transformers and similar inductive loads, preventing nuisance tripping.
- Current-Limiting: Limits peak let-thru currents to protect the system from potential damage.
- Rejection-Style Design: Reduces the risk of incorrect fuse replacements when used with recommended fuse blocks.
- High-Visibility Orange Label: Ensures quick identification and ease of replacement.
- Traceability: Includes a metal-embossed date and catalog number for easy identification and tracking.
- Durable Construction: The fiberglass body withstands harsh industrial environments, providing dimensional stability.
- Efficient Arc Quenching: Uses high-grade silica filler to rapidly quench arcs and maintain high current limitation.
