Eaton STS368FW3 Shunt Trip Safety Switch - UL Listed

The STS368FW3 is a three-pole, heavy‑duty shunt-trip safety switch with a 600 Vac main voltage and a 120 Vac coil. Business Impact: This combination enables rapid remote isolation of high‑current equipment, reducing arc flash exposure and downtime during maintenance or fault events. Application: It is well suited for motor control centers and critical process lines in manufacturing facilities where fast, controlled shutdowns are essential. The unit is housed in a NEMA 4X enclosure and carries UL Listed and cUL Certified ratings. Business Impact: It stands up to exposure to dust, water ingress, and corrosion in tough plant environments, lowering enclosure failures and maintenance costs. Application: Ideal for outdoor installations, washdown areas, and rugged plant floors in food, beverage, and chemical processing facilities. Integrated fusible protection supports an interrupting capacity of 1200 A and a voltage rating of 600 Vac / 250 Vdc. Business Impact: Enables selective coordination with upstream devices and reduces outages caused by fuse-related faults. Application: Useful in main switchgear, power distribution blocks, and safety interlock assemblies in industrial settings. The 120 Vac coil enables straightforward integration with existing control systems and remote-tripping schemes. Business Impact: Lowers retrofit costs and simplifies control panel upgrades while preserving fail-safe operation. Application: Plant-wide safety interlock programs and automation lines that require fast, remote shutdown capability. Robust construction with dimensions and weight—23.15 in L, 47.23 in W, 72.5 in H, and 405 lb—support long service life and stable operation in vibration-prone facilities. Business Impact: Reduces maintenance frequency and improves reliability in harsh environments. Application: New installations in large switchgear or retrofits where structural rigidity and durable performance matter.
