Eaton Specification Sheet - STS368FW32
The 1200 A amperage rating provides a high interrupting capacity, enabling reliable fault isolation for heavy-duty power distribution while reducing the risk of equipment damage and unscheduled downtime. The 120 Vac control coil is compatible with standard industrial control circuits, allowing quick remote actuation without custom interfaces and improving control-system consistency. The three-pole, fusible design ensures all conductors are safely disconnected during a trip, delivering predictable coordination with upstream protective devices and simpler troubleshooting in motor control centers. The NEMA 4X enclosure delivers rugged protection against moisture, dust, and washdown, enabling outdoor and harsh-environment installations with minimal enclosure maintenance. UL Listed and cUL Certified markings support compliant procurement and cross-border deployment, aligning with corporate safety programs and audit requirements. Catalog number STS368FW32 and the integrated protection scheme simplify ordering and integration with existing Eaton protection devices, streamlining project timelines and maintenance planning for industrial protection devices.
