Overview
The Gould Shawmut TRS1-8/10R is a Tri-Onic current-limiting time-delay fuse engineered for overcurrent protection in motor circuits, transformers, service entrance equipment, feeder and branch circuits. Rated at 1.8 amperes and 600 volts AC, this Class RK5 fuse combines fast response to faults with tolerance for harmless inrush currents typical in motor applications.
Key Features
- Time-Delay Design: Safely handles motor starting currents and transformer inrush without nuisance trips
- Current-Limiting Technology: Restricts fault current to reduce equipment stress and damage risk
- Class RK5 Rating: UL and CSA certified for industrial and commercial use
- 200kA Interrupting Rating: Provides robust overcurrent protection up to fault levels of 200,000 amperes
- Ferrule Terminal Configuration: Ensures secure insertion and consistent electrical contact in cartridge-style fuse holders
- Non-Indicating Design: Clear indication of fuse status without mechanical failure indicators
