Eaton STS366FW61 Shunt Trip Safety Switch - UL/NEMA4X

Feature 1: Shunt trip safety switch with three-pole design enables remote tripping of power circuits, delivering faster fault response and enhanced operator safety in motor control centers and switchgear assemblies. This directly reduces arc exposure and potential damage, supporting safer plant shutdowns and compliance with industrial safety programs. Application: MCCs in manufacturing lines and automated cells benefit from immediate tripping when safety interlocks are triggered. Feature 2: 304 stainless steel enclosure with a NEMA 4X rating resists corrosion and washdown. This extends service life in demanding environments such as harsh industrial floors and outdoor installations, lowering maintenance costs and reducing unplanned downtime. Application: food & beverage, chemical processing, and outdoor control panels. Feature 3: 600 A amperage rating and 600 Vac / 250 Vdc voltage with a 24 Vdc coil support high-load circuits while integrating with standard control logic. This minimizes the need for alternative protection devices and simplifies wiring, improving installation efficiency. Application: heavy machinery, conveyors, and large MCCs. Feature 4: Alarm switch auxiliary contact (1 NO-1 NC) enables signaling for remote monitoring and interlocks. This improves fault diagnostics, reduces mean time to repair, and supports safer shutdown sequences. Application: panel alarms, PLC interfaces, and control-system signaling. Feature 5: Fusible protection and UL/cUL certifications provide compliance with safety standards, reducing procurement risk and expediting audits. Application: safety-critical industrial environments where regulatory compliance matters. Feature 6: Clear dimensional footprint and weight (12.43 in L, 28.29 in W, 62.97 in H, 145 lb) assist with space planning in existing racks and new installations. This facilitates accurate enclosure planning and mounting considerations. Application: engineering design reviews and panel retrofits.
