Description
The Mersen TRM6/10 Tri-Onic® Midget Time-Delay Fuse provides reliable supplemental overcurrent protection for small motors, transformers, and high-inrush electronic loads operating up to 250 VAC. Engineered with a 12-second time-delay at 200% rating, this 0.6A midget fuse safely absorbs harmless startup and inrush currents without nuisance tripping.
Built in the compact 1-1/2″ x 13/32″ (10.3 x 38.1 mm) standard midget dimension, the TRM6/10 features tin-plated copper ferrule terminals and a durable GMG body. *(Note: Designed for supplemental protection and is not rated for branch circuit protection).*
Key Features
- Time-Delay Performance: Features a 12-second time-delay at 200% rating to accommodate motor starting and transformer inrush currents.
- 250V AC Rating: Optimized for supplemental protection in control circuits, lighting ballasts, and small inductive loads up to 250 VAC.
- Compact Midget Dimensions: Industry-standard 10.3 mm x 38.1 mm (1-1/2″ x 13/32″) footprint fits standard midget fuse holders and blocks.
- Tin-Plated Copper Terminals: High-conductivity ferrule connections ensure secure electrical contact and corrosion resistance.
- Durable GMG Body Construction: Molded from robust glass-melamine (GMG) material for excellent thermal stability and arc quenching.
