Bussmann series Fuseology
Bussmann series Low-Peak 600 V LPS Class RK1 time-delay fuses, up to 600 A data sheet no. 1001
Feature: Time-delay, dual-element design is engineered to tolerate inrush currents while delivering a measured interruption when a fault occurs. Impact: Reduces nuisance trips and unplanned shutdowns, improving overall line reliability. Application: Ideal for motor starters and control circuits where brief surges are common, such as conveyors and presses, enabling smoother startup without compromising protection. Feature: 17.5 A rating at 600 Vac and 300 Vdc with a 600 Vac / 300 Vdc rating provides broad compatibility across industrial power systems. Impact: Supports standardization of protection across mixed-voltage equipment, reducing the number of spare parts required. Application: Suitable for mixed-control panels and machine centers with multi-voltage loads. Feature: Class RK1, current-limiting, non-indicating fuse delivers predictable protection with minimal maintenance. Impact: Streamlines stocking and replacement, lowers maintenance downtime, and supports consistent safety margins. Application: Fits Bussmann RK1 family products in new builds and retrofits. Feature: Ferrule end to ferrule end connection simplifies wiring and field replacements. Impact: Improves installation speed and reduces wiring errors, shortening commissioning times. Application: Panel assemblies and machine upgrades where quick swap-outs are valuable. Feature: High interrupt rating of up to 300 kAIC at 600 Vac and 100 kAIC at 300 Vdc provides robust fault handling. Impact: Enables protection for high-energy circuits and critical loads, reducing the risk of catastrophic failures. Application: Main feeds and heavy machinery contactors in industrial environments. Feature: Non-indicating fuse indicator avoids visual clutter while maintaining reliable fault signaling through electrical testing. Impact: Cleaner panel aesthetics and straightforward diagnostics. Application: Panels with multiple protection devices where indicator visibility is managed via separate monitoring.
