Cooper Power Systems CMU Power Fuse — CMU702100
The Eaton Cooper Power Systems CMU702100 is a K-speed power fuse rated at 100 amperes and 17 kilovolts for medium-voltage distribution applications. Standing 19.1 inches tall, this CMU series fuse provides reliable overcurrent protection in overhead distribution fuse cutouts and switchgear installations.
Key Specifications
- Ampere Rating: 100 A
- Voltage Rating: 17 kV
- Fuse Speed: K
- Overall Height: 19.1 in.
- Manufacturer: Cooper Power Systems (Eaton)
- Model: CMU702100
Applications
Used in medium-voltage overhead distribution systems for protecting transformers, feeder circuits, and branch laterals rated through 17 kV. The 100A rating accommodates larger distribution loads compared to lower-rated CMU fuses, while the K speed characteristic provides the appropriate time-current characteristic for transformer and feeder protection coordination.
