Fuse 250V 450A Time-Delay Class RK5 TR Series Smart-Spot
Product Description
The Tri-Onic TR-R time-delay fuses are designed specifically for current-limiting applications, providing effective overcurrent protection for motors, transformers, service entrance equipment, feeders, and branch circuits. With a rated voltage of 250V AC and 160V DC, these fuses are suitable for use in 50/60 Hz electrical systems.
One of the key features of the TR-R series is its time-delay characteristic, which safely accommodates harmless starting currents and inrush currents commonly associated with modern motors and transformers. The maximum interrupting rating for AC is 200 kA, ensuring reliable performance under fault conditions.
The fuse is equipped with a SmartSpot® indication system, which enhances visibility for maintenance and operational checks. Constructed with a tin-plated copper terminal type and housed in a durable PolyTube body, the fuse is both efficient and compliant with ROHS standards.
Measuring 10.38 inches in length and 2.56 inches in diameter, with a weight of 3.1 lb, this fuse is designed for clip mounting, facilitating easy installation in various applications.
