Eaton Specification Sheet - BG3031SQ
Feature → Business Impact → Application: The BG3031SQ supports a 25-30 A, 480 V rating with a Class G fuse block design, enabling safe protection for mid-range circuits while keeping panel density manageable. This translates to reduced fault risk in motor control circuits and easier integration into existing control cabinets, particularly in packaging, material handling, and process lines. Application: Ideal for machine and line protection where standard 480 V feeders require reliable 25-30 A protection with a compact footprint. Feature → Business Impact → Application: Screw termination with #14-10 AWG Cu wires provides secure, vibration-resistant connections that minimize loose-terminal failures in harsh environments. Benefit: Improves uptime and simplifies field servicing during routine maintenance or upgrades. Application: Suitable for retrofit projects or new builds in 480 V control panels, C-level automation cabinets, and regional distribution panels. Feature → Business Impact → Application: Thermoplastic housing and RoHS compliance deliver chemical resistance and regulatory assurance in industrial spaces with solvents or cleaning processes. Benefit: Lowers compliance risk and reduces total cost of ownership. Application: Industrial warehouses, food & beverage processing lines, and packaging lines where RoHS compliance and environmental resilience are required. Feature → Business Impact → Application: 100 kAIC interrupt rating and 100 kA short-circuit rating provide strong protection against high-energy faults. Benefit: Minimizes damage to downstream components and reduces outage duration. Application: Main or feeder protection in MCCs and switchgear assemblies where high fault currents may occur. Feature → Business Impact → Application: UL Recognized and CSA Certified status simplify procurement, QA audits, and regulatory acceptance. Benefit: Accelerates project approvals and supports supplier qualification programs. Application: Global manufacturing sites and multi-national facilities requiring consistent compliance labeling.
