Eaton STS368NW31-1B00 Shunt Trip Safety Switch - NEMA 4X

Feature: The STS368NW31-1B00 offers a robust 1200 A amperage rating with fusible protection, delivering reliable isolation for high-current feeders. Business impact: This capability limits fault currents and reduces arc-flash risk during maintenance or fault events, helping facilities meet strict safety standards. Application: It is well suited for motor control centers, main lugs, and critical feeders in industrial plants where downtime is costly and uptime is mission-critical. Feature: Three-pole configuration with a 120 Vac coil provides synchronized actuation across all phases, enabling consistent fault clearance. Business impact: Simplifies wiring, improves phase balance, and supports faster, safer trips in demanding electrical environments. Application: Ideal for switchgear, MCCs, and heavy-duty control panels requiring reliable multi‑pole isolation. Feature: NEMA 4X enclosure offers rugged protection against dust, moisture, and wash-downs. Business impact: Reduces corrosion risk and maintenance cycles in outdoor or harsh indoor environments. Application: Suitable for outdoor installations, wet plants, and other demanding locations. Feature: Includes integrated alarm and sensing options—1NO/NC Alarm Switch, 480V CPT, and GF Relay & Sensors. Business impact: Enables proactive fault signaling and diagnostics within the protection scheme, improving uptime and safety monitoring. Application: Helpful for plant-wide safety interlocks and condition-based maintenance programs. Feature: Large footprint with 23.15 in depth, 72.5 in height, 47.23 in width, and a 405 lb weight. Business impact: Requires planned installation in appropriate switchgear footprints but provides substantial protection for critical feeders and high-current circuits. Application: Best suited for centralized protection in main switchgear rooms and control centers.
