Overview

The Mersen TRS45RDC is a Class RK5 time-delay fuse engineered for DC circuit protection in harsh industrial environments. Rated at 600VDC and 45A, this Tri-Onic® fuse is specifically designed for mine duty applications, including surface and underground mining operations. Its time-delay characteristic allows it to handle motor start-ups and high inrush loads without nuisance openings, ensuring operational continuity. The fuse features a rugged glass melamine body for superior reliability in extreme conditions. With a 20kA interrupting rating (IR) DC, the TRS45RDC meets stringent third-party requirements, including MSHA approval (no. 28-26-0). It is UL/CSA listed for power fuses and is available with optional blown fuse visual indication (add 'ID' to the catalog number, e.g., TRS45RID). Tin-plated end caps are offered on non-ID fuses under 60A. Compatible fuse blocks for 31-60A ratings include 1-pole or 3-pole 600V options. The TRS-RDC series spans 1/10 to 400A, with 300VDC ratings for 0.1-30A and 600VDC for 35-400A. Key applications include mine circuits, trailing cables, pump motors, and rail heaters.
