Description
Tri-Onic TR-R current-limiting time-delay fuses are engineered for overcurrent protection of motors, transformers, service entrance equipment, feeders and branch-circuits. The time-delay characteristics of the TR-R safely handle harmless starting currents and inrush currents associated with today's motors and transformers.
Features
- Engineered with a robust Tri-Onic® time-delay characteristic, this fuse safely handles harmless inrush currents and temporary surges up to 500% of its rating for a minimum of 10 seconds. This essential feature eliminates expensive nuisance downtime in industrial facilities, ensuring heavy-duty 250V motors, commercial HVAC systems, and transformers start smoothly while still providing ultimate overcurrent protection against sustained overloads.
- Boasting a massive 200,000 Amp short circuit current rating (SCCR) at 250V AC, this highly efficient current-limiting fuse restricts fault currents before they can cause severe thermal or magnetic damage. By rapidly clearing high-fault electrical events, it actively protects your valuable switchgear, electrical distribution panels, and personnel from severe hazards, minimizing equipment repair costs and maintaining strict workplace safety.
- Designed with standard Class RK5 rejection dimensions, this 200-amp cartridge fuse is engineered to fit perfectly into specialized rejection clips, preventing the dangerous accidental installation of lower-rated, non-current-limiting Class H fuses. This fail-safe mechanical footprint guarantees your commercial electrical infrastructure remains properly rated, simplifying routine panel maintenance and retrofitting for facility electricians.
- Fully UL Listed to standard 248-12 and CSA Certified to standard C22.2, this industrial-grade overcurrent protection device ensures your commercial installations easily pass strict local safety inspections. Relying on factory-tested, code-compliant hardware guarantees highly reliable performance across harsh manufacturing environments and ensures your facility's operational liability insurance remains strictly valid.
