Selling Policy 25-000 - Distribution and Control Products and Services
High-current, three-pole design delivers robust protection for heavy feeders with a system voltage of 480 V and a control voltage of 120 V. This configuration supports reliable motor and equipment protection, reducing unplanned downtime and extending asset life in demanding production lines. The bottom feed/fuse configuration simplifies wiring and enclosure layout, enabling faster installation and easier serviceability in retrofit projects. Interlock with no-light functionality (BFD) provides clear, fail-safe switching to prevent accidental closures, while the fault-tolerant ground fault option enhances personnel safety and reduces arc-flash exposure in critical services. The fusible protection scheme aligns with established electrical codes, supporting compliance and predictable fault clearing. NEMA 1, 3R, 4, and 12 compatibility broadens enclosure options, improving installation versatility across factory floors. Optional features such as Ground Fault Relay, Blown Fuse Detection, and Auxiliary Contacts extend protection and monitoring without sacrificing compact installation. Overall, this switch combines high performance with practical installation, yielding tangible efficiency gains, improved safety, and lower total cost of ownership in switchgear assemblies.
