FAQs
STS367FW11 requires a suitable three-pole mounting within a compatible enclosure. Ensure a NEMA 4X rated environment and 304 stainless steel construction for corrosion resistance. Verify 600 Vac / 250 Vdc ratings and a 24 Vac coil to match your control circuit, and confirm auxiliary alarm wiring (1 NO-1 NC) is routed to the control/PLC input for proper signaling.
Key specs include an 800 A amperage rating, three poles, 24 Vac coil voltage, and protection classified as fusible. The voltage rating covers 600 Vac and 250 Vdc, with a 1 NO-1 NC auxiliary contact for alarm signaling, enabling reliable fault interruption in high-energy circuits.
Yes. The three-pole, 800 A rating and 24 Vac coil are designed for high-current MCC and switchgear applications. Its NEMA 4X enclosure and 304 stainless steel construction support harsh environments, while the alarm contact supports integration with MCC annunciators and control systems.
STS367FW11 is UL Listed and cUL Certified, ensuring North American regulatory compliance for safety and performance. This reduces the need for additional third-party verification and streamlines procurement for facilities requiring standard safety approvals in industrial settings.
The rugged 304 stainless steel NEMA 4X enclosure minimizes corrosion-related maintenance, while the clear alarm signaling and reliable tripping reduce unplanned downtime. The combination of high-current protection and industry certifications supports long service life and a favorable total cost of ownership in demanding industrial environments.
