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
- The Mersen TRS50R is engineered with a dual-element design that provides a minimum 10-second time-delay at 500% of the rated current. This allows the fuse to "ride through" the temporary startup surges of 600V motors and transformers, preventing nuisance trips while still providing sensitive protection against long-term overloads.
- As a Class RK5 current-limiting fuse, the TRS50R reacts to short circuits with extreme speed, clearing faults before the current can reach its full destructive peak. This significantly lowers the "let-through" energy (I^2t), shielding your contactors, breakers, and bus bars from the thermal and magnetic stresses of a major fault.
- Boasting a 200,000 Amp Interrupting Rating (AIC) at 600V AC, this fuse is built to safely clear even the most catastrophic short circuits. This industry-leading capacity ensures the fuse can manage high-energy faults without internal failure, safeguarding personnel and maintaining the integrity of your facility’s electrical infrastructure.
- The TRS50R features the Class R rejection-style grooved end-cap. When used with a compatible Class R fuse block or disconnect, this physical design prevents the accidental installation of lower-rated, non-current-limiting Class H or K fuses, ensuring your system always maintains its engineered safety level and remains code-compliant.
- Rated for up to 600V AC and 300V DC, the TRS50R is a highly versatile choice for various Canadian industrial applications. Its 300V DC rating makes it an excellent option for specialized machinery, battery storage systems, and solar combiner boxes where reliable DC overcurrent protection is required.
