Shawmut TRS 300 Tri-Onic® Time Delay Fuse, 600AC/300DC 300Amp, Class K-5

The Shawmut TRS 300 Tri-Onic® is a 300-amp, time-delay fuse designed for overcurrent protection in industrial and commercial electrical systems. It operates at 600 volts AC and 300 volts DC and is classified as a Class RK5 fuse. Key Features: Time-Delay Functionality: Allows temporary inrush currents, such as motor startups and transformer energization, to pass without causing nuisance trips. Current-Limiting Design: Reduces peak let-through current, minimizing potential damage to downstream equipment. High Interrupting Rating: Capable of handling fault currents up to 200,000 amperes AC and 100,000 amperes DC. Physical Specifications: Diameter: Approximately 2-9/16 inches (65.02 mm) Length: Approximately 11-5/8 inches (295.4 mm) Construction: Cylindrical body with knife blade terminals for secure and easy installation. Applications: Motor Circuits: Provides protection against overcurrents while allowing for startup surges. Transformers: Ensures safe operation by tolerating initial energization surges. Service Entrance Equipment: Protects main service panels and electrical distribution systems. Feeders and Branch Circuits: Maintains system integrity by preventing overcurrent damage.
