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 TRS25R features a sophisticated 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 high-current inrush of motors and transformers, eliminating nuisance blowing while still providing precision protection against sustained overloads.
- As a current-limiting Class RK5 fuse, the TRS25R reacts to short circuits with extreme speed, clearing faults before the current can reach its full destructive peak. This significantly reduces the "let-through" energy ($I^2t$), shielding your contactors, breakers, and bus bars from the thermal and magnetic stress of a fault.
- Boasting a 200,000 Amp Interrupting Rating (AIC) at 600V AC, this fuse is engineered to safely clear even the most catastrophic short circuits. This industry-leading capacity ensures that the fuse can manage high-energy faults without internal failure, protecting both your personnel and your facility's infrastructure.
- The TRS25R features the Class R rejection-style grooved end-cap. When paired with a Class R fuse block, this physical characteristic prevents the accidental installation of lower-rated, non-current-limiting Class H or K fuses, ensuring your system always maintains its engineered safety and code compliance.
- Rated for up to 600V AC and 300V DC, the TRS25R is a versatile solution for a wide range of Canadian industrial applications. Its ability to handle DC circuits makes it an excellent choice for specialized machinery, solar arrays, and battery backup systems where reliable protection is paramount.
