TR15R - 15 Amp Fuse

TR15R - 15 Amp Fuse

The Mersen TR15R is a 15-amp, Class RK5 time-delay fuse in the Tri-Onic® TR-R series, designed to protect your industrial and commercial electrical systems from overcurrent. Rated for 250VAC and 160VDC, this current-limiting fuse combines time-delay operation with a compact ferrule-style design. It is intended for applications involving motors, transformers, service entrance equipment, feeders, and branch circuits where the electrical system calls for a 15A Class RK5 fuse with the appropriate voltage and interrupting ratings.
