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
- Boasting a robust 400-amp capacity and a versatile 250V rating, this large-frame Tri-Onic® fuse is designed for heavy-to-extreme power distribution networks. It serves as a reliable main or branch circuit safeguard in industrial switchboards, feeder panels, and motor control centers, keeping high-capacity power lines securely protected.
- Featuring a massive 200,000-amp AC interrupting capacity (and 20kA DC), this current-limiting fuse rapidly clears extreme electrical faults before they can damage downstream equipment. Its exceptional current-limiting capabilities dramatically reduce peak let-through energy, preventing explosive arc flash incidents and safeguarding your facility's personnel and infrastructure.
- Constructed with a premium, dimensionally stable fiberglass tube rather than traditional paper-based materials, this unit delivers superior structural integrity and moisture resistance. It prevents the internal swelling, tracking, and degradation common in humid processing plants or unconditioned outdoor enclosures, guaranteeing reliable overcurrent protection over an extended operational lifespan.
