Eaton STS366UW6 Shunt Trip Safety Switch - NEMA 4X

Feature → Business Impact → Application. The shunt trip mechanism provides rapid circuit isolation on demand, reducing exposure to arc flash and enabling safer maintenance in MCCs and switchgear. This directly improves safety metrics and uptime in heavy industry environments where downtime is costly and safety is non-negotiable. Application: emergency shutdowns in motor control centers and feeders benefit from predictable response times and robust protection. The 304 stainless steel NEMA 4X enclosure offers corrosion resistance and washdown compatibility, lowering maintenance cycles and extending service life in chemical plants and food & beverage facilities. Application: environments with aggressive sanitizing or cleaning protocols demand durable enclosures that resist corrosion and ingress. The 600 A amperage rating, 600 Vac/250 Vdc voltage rating, and 24 Vdc coil enable seamless integration with existing protection schemes while keeping wiring complexity manageable; non-fusible design simplifies service and reduces arc energy concerns in utility and process automation installations. Application: high-current safety applications in panelboards and switchgear trains where reliability and ease of replacement matter. UL Listed and cUL Certified status supports audit-ready safety compliance, procurement confidence, and smoother cross-border installations; this is reinforced by the unit’s three-pole configuration for balanced fault isolation. Application: multinational projects and EPCs prioritizing standards compliance. The included warranty and Eaton support resources help minimize total cost of ownership, improving ROI for safety upgrades in aging facilities.
