FAQs
When installing the 1BS104, ensure wiring uses Cu or Al conductors within the #4-500 kcmil range and employs the set screw connections mounted on the stud. Verify clearance for the 1 in by 1 in base footprint and follow manufacturer torque guidelines from the datasheets to maintain reliable electrical contact and vibration resistance in industrial panels.
Key specifications include a 600 A amperage rating, 200 kAIC interrupt rating, and a 600 V voltage rating. The assembly uses a molded black phenolic base with tin-plated aluminum connectors and zinc-plated steel studs. Wire size compatibility is #4-500 kcmil Cu/Al, with set-screw connections and stud mounting for robust installation.
Yes. The 1BS104 is designed as a modular universal fuse block suitable for motor control centers (MCCs) and power distribution panels. Its high interrupt rating and modular form factor support scalable protection schemes, while the set-screw terminals and durable materials ensure reliable operation in demanding environments.
The 1BS104 is RoHS compliant, aligning with restricted substances requirements. While RoHS is confirmed, for additional certifications such as CE or UL, consult Eaton datasheets and factory documentation to verify current listing status and any region-specific approvals.
The modular design reduces spare-parts variety and simplifies field configuration, cutting maintenance time during upgrades or expansion. High current capability and simple set-screw connections decrease downtime during fault isolation, improving overall equipment availability and reducing labor costs in routine servicing and panel reconfigurations.
