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 an advanced dual-element time-delay characteristic, this 8-amp fuse safely absorbs harmless transient inrush currents and transformer inductive surges. By tolerating temporary startup spikes without opening, it eliminates frustrating nuisance trips, keeping your industrial pumps, small motors, and conveyor systems running smoothly without sacrificing overcurrent protection.
- Boasting an exceptional 200,000-amp AC interrupting rating at 250V, this Class RK5 fuse delivers critical, high-level current limitation. It violently quenches high-energy short circuits before peak let-through current can destroy downstream control components, protecting sensitive machinery and drastically lowering your facility’s arc-flash hazard risk.
- Featuring standard Class RK5 dimensions (2 in times 9/16 in with a ferrule terminal structure), this fuse incorporates a mechanical rejection footprint. When paired with an RK5-compatible fuse block, it physically prevents a technician from accidentally inserting a lower-rated Class H or K fuse, ensuring your engineered protection parameters remain strictly uncompromised.
- Built with a premium fiberglass body and an inner high-grade silica filler, the fuse provides excellent dimensional stability and superior arc suppression. It resists structural degradation from moisture, vibration, and thermal cycling, ensuring the component won't split, crack, or misalign inside highly demanding industrial control panel environments.
- Carrying a versatile dual rating of 250V AC and 160V DC, this single component easily bridges the gap between different power architectures. It allows industrial inventory managers and field electricians to standardize their stock, successfully covering motor circuits, mains, feeders, and solar/battery DC sub-systems with one highly reliable line.
