Overview

The Mersen TRS1-4/10RDC is a Class RK5 time-delay fuse engineered for DC circuit protection in surface and underground mining applications. Rated at 300VDC and 1.4A, this Tri-Onic® ferrule fuse delivers reliable performance in harsh environments with a 20kA interrupting rating for DC systems. Its time-delay characteristic safely accommodates motor start-ups and high inrush loads, preventing nuisance openings in trailing cables, pump motors, and rail heaters. 28-26-0) and adheres to stringent third-party requirements for 600VDC-rated fuses. The rugged glass melamine body ensures dimensional stability and superior reliability under extreme conditions, while the fiberglass construction enhances durability. A rejection-style design eliminates replacement errors, and metal-embossed date/catalog markings enable full traceability. Compatible with Mersen fuse blocks (e.g., 20306R, 20308R for 250V; 60306R, 60308R for 600V), this fuse integrates seamlessly into existing mine duty circuits. Optional blown fuse visual indication (add "ID" suffix) provides enhanced monitoring capabilities. With a minimum trip indicator operating voltage of 90V, it supports critical DC applications requiring precise overcurrent protection.
