Description
Tri-Onic TRS-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 TRS-R safely handle harmless starting currents and inrush currents associated with today's motors and transformers.
Features
- Engineered with Mersen’s Tri-Onic® dual-element technology, this 125-amp fuse provides a minimum 10-second time-delay at 500% of its rated current. This prevents the "nuisance tripping" commonly caused by high inrush currents from large industrial motors or transformer loads, ensuring your facility remains operational without sacrificing precision overcurrent protection.
- Rated for both 600VAC and 600VDC applications, the TRS125R is a highly versatile solution for industrial power distribution, motor control centers, and renewable energy systems. This dual-voltage capability simplifies your inventory by allowing one fuse to serve as a reliable safety backup for a wide range of heavy-duty commercial equipment and machinery.
- Featuring a high interrupting rating of 200,000 Amps, this fuse is designed to "limit" the peak let-through current during a short circuit event. By rapidly clearing faults, it significantly reduces the destructive thermal and magnetic forces that can vaporize wiring and shatter downstream components, safeguarding your expensive electrical infrastructure and improving overall arc-flash safety.
- Built with specialized Class RK5 rejection dimensions, this blade-style fuse is designed to be installed only in compatible RK5 fuse clips. This critical physical safety feature prevents the accidental insertion of non-current-limiting Class H or K fuses, ensuring your electrical system maintains its engineered protection levels and strictly adheres to NEC and UL 248-12 safety standards.
- Constructed with high-grade materials and a rugged body, the TRS125R is built to withstand the vibration and temperature fluctuations typical of manufacturing plants and utility rooms. The silver-plated copper blades ensure low-resistance connections and cooler operation, extending the lifespan of your fuse holders and reducing the frequency of maintenance-related downtime.
