Overview
The Bussmann RES-60 is a time-delay renewable fuse designed for 600V three-phase and single-phase industrial circuits. These non-current-limiting Class H fuses are ideal for applications where frequent service interruptions justify the economy of renewable (replaceable) elements rather than one-time fuses. This lot contains 5 individual units ready for immediate installation or stocking.
Key Features
- 600V AC rated for industrial and commercial panel protection
- 60A continuous current rating with time-delay (Super Lag) response
- Renewable element design—replace the internal link instead of the entire fuse body
- Ferrule-end configuration for standard Class H fuse blocks
- 10 kA interrupting rating at 250 VAC per UL 248
- Non-current-limiting type suitable for circuits with fault current under 10,000 amps
