The BUSSMAN 170M7083 is a high-speed semiconductor (aR) square-body fuse engineered for reliable overcurrent protection in demanding UPS and power-electronic applications. Designed for critical protection of rectifiers, inverters, and common-bus rails, this fuse interrupts fault currents rapidly to safeguard semiconductors and uptime.
Ultra-Rapid aR Curve:
Purpose-built for semiconductor circuits where fast, precise interruption is essential.
Size-4 Square-Body:
4BKN/65 form factor with flush-end M10 terminals on 66.6 mm centers for drop-in replacement.
High Fault Withstand:
690 V AC rating with 200 kA interrupting capacity and center Type K indicator for clear blown-fuse status.
Cost-Effective Options:
Available as new OEM stock or reclaimed from decommissioned, fully functional UPS units, each fuse continuity-tested and verified.
