TRS40R - 40 Amp Fuse Description
TRS40R - 40 Amp Fuse
The TRS40R 40 Amp Fuse from Tri-Onic delivers dependable overcurrent protection for electrical systems that need consistent, uninterrupted performance. Built for both industrial and commercial power applications, this Class RK5 time-delay fuse is designed to protect motors, transformers, feeders, and service entrance equipment from overloads and short circuits—without tripping during normal start-up surges. Its precision-engineered time-delay feature allows it to handle heavy inrush currents safely, helping your equipment run smoothly and stay protected even under demanding conditions. With a high interrupting rating and strong insulating PolyTube body, the TRS40R fuse ensures lasting safety and reliability across both AC and DC circuits up to 600 volts.
