Eaton Specification Sheet - STS367FP11
High-current capability and three-pole design enable rapid isolation of large loads, reducing the risk of cascade faults and enabling safer downstream testing and maintenance. The 800 A rating supports motor control center feeders and heavy machinery, delivering measurable uptime improvements in demanding facilities. Shunt trip coil operation at 24 Vac allows remote triggering from PLCs or safety interlocks, accelerating fault clearance and minimizing production interruptions. The alarm contact (1 NO/NC) provides immediate status signaling to BMS or PLC-based safety logic, enhancing plant-wide visibility and traceability. A rugged NEMA 4 enclosure in painted steel protects against dust, splashes, and weather-related ingress, extending service life in outdoor or damp environments. Certifications such as UL Listed and cUL Certified simplify procurement and compliance documentation for regulated industries. The compact three-pole design ensures full isolation of three-phase circuits, improving fault containment and reducing the likelihood of partial energization during maintenance. These features translate to lower life-cycle costs, easier installation with standard controls, and better alignment with industry safety standards.

FAQs
STS367FP11 is a three‑pole shunt trip safety switch designed for integration with standard motor control centers. Ensure mounting to a compatible enclosure with NEMA 4 protection and verify clearances for the 12.43 in depth, 29.54 in width, and 71.72 in height as documented. Confirm 24 Vac coil control wiring and 600 V maximum rating to align with your control logic and safety interlocks.
Key specs include an 800 A amperage rating, 24 Vac coil voltage for remote trip, 600 V voltage rating, and a 1 NO/1 NC alarm contact configuration. It is a three-pole device with a NEMA 4 enclosure, suitable for industrial environments and high-current safety applications.
Yes. The unit features a NEMA 4 enclosure and painted steel construction, providing protection against dust, water, and mild corrosives typical in industrial settings. This makes it appropriate for outdoor or damp locations when integrated with appropriate installation practices and standard electrical protection schemes.
STS367FP11 carries UL Listed and cUL Certified markings, underscoring electrical safety and conformity to applicable North American standards. These certifications assist with procurement, installation approvals, and regulator-facing documentation for compliance-heavy projects.
Warranty follows Eaton policy 25-000: one year from installation or eighteen months from shipment, whichever comes first. For ongoing reliability, perform periodic functional checks of the 24 Vac coil, alarm contact, and overall enclosure integrity, and verify that remote trip signals and signaling circuits remain error-free as part of preventative maintenance.
