Overview
The Gould Shawmut TRM6 is a time-delay midget fuse offering supplemental protection for industrial and commercial electrical systems. This lot includes 7 units rated at 6 amperes, 250V AC. The Tri-Onic® design provides reliable overcurrent protection with a 12-second time delay at 200 percent rated load, making it ideal for circuits with high inrush currents such as small motors and transformers.
Key Features
- Tri-Onic® time-delay (slow-blow) operation prevents nuisance trips on motor startup and transformer energization
- Midget cartridge form factor: 1-1/2″ length × 13/32″ diameter for compact panel mounting
- Ferrule terminals for secure cartridge holder installation
- 10 kA interrupting rating provides adequate fault protection
