Overview
The Gould Shawmut TRM2 is a time-delay Tri-Onic cartridge fuse rated 2A at 250VAC. It is designed for supplemental overcurrent protection of small motors, transformers, and high-inrush circuits where conventional fast-blow fuses would nuisance-trip. This midget fuse meets UL and CSA standards for industrial and commercial applications.
Key Features
- Tri-Onic time-delay technology safely handles harmless motor starting and inrush currents
- 2A amperage rating with 250VAC voltage rating
- 10 kA interrupt rating for reliable fault clearing
- Midget cartridge form factor: 0.41″ diameter × 1.5″ length
- UL and CSA certified; RoHS compliant
- 10 pieces per box for bulk protection needs
