Mersen TRM-210 Tri-Onic® Time-Delay Midget Fuse, 250VAC Ferrule

Mersen TRM-210 Tri-Onic® Time-Delay Midget Fuse, 250VAC Ferrule

The Mersen Tri-Onic® TRM Series is a family of Time-Delay Midget-class fuses rated 250V AC and available in ferrule-terminal, clip-mount configurations spanning ampere ratings from 1/10 to 30A. Within this platform, the Motor FLA selection covers 12 options — 0.2A, 0.3A, 0.4A, 0.8A, 1.125A, 1.6A, 1.8A, 2.5A, 2.8A, 3.5A, 4.5A, and 5.6A — letting you match the fuse precisely to the full-load amperage of the motor or transformer being protected. Every option in the family shares the same 12-second time-delay at 200% rating, a GMG body/insulating material, tin-plated copper Ferrule terminals, and a 10 kA AC interrupt rating, delivering dependable supplemental protection against high-inrush loads on small motors, small transformers, and other general 250V AC equipment. These fuses are intended for supplemental protection only and are not designed for Branch Circuit Protection.

Key Features
