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® time-delay technology, this 400-amp fuse provides a minimum 10-second opening delay at 500% of the rated current. This allows for high-torque industrial motors and large transformers to draw initial inrush current without causing nuisance trips, significantly reducing unnecessary downtime in high-output manufacturing environments.
- With a massive 200,000 Amp interrupting rating at 600V AC, this current-limiting fuse rapidly clears high-energy faults before they can damage downstream equipment. This extreme level of protection is critical for industrial service entrances and main distribution panels, ensuring that your expensive electrical infrastructure remains shielded from the destructive thermal and magnetic forces of a major short circuit.
- Designed with specialized rejection-style blade terminals, this fuse is specifically keyed to fit Class R fuse holders, preventing the accidental installation of standard Class H or K fuses that lack current-limiting capabilities. This physical safeguard ensures that your system maintains its high Short Circuit Current Rating (SCCR), keeping your facility in strict compliance with NEC and CEC safety requirements.
- he advanced dual-element design provides precision protection against low-level overcurrents as well as high-capacity short circuits. This versatility makes it the "all-purpose" choice for protecting everything from branch circuits and feeders to specialized industrial machinery, simplifying your inventory management by serving as a single, reliable solution for multiple 600V applications.
