The STS367ND11 delivers an 800 A rating with a three-pole design, enabling direct protection of large feeders and motor circuits while reducing panel clutter and wiring complexity. This improves reliability and shortens fault clearance times in MCCs and switchgear used in heavy industry. The 24 VAC coil paired with a 1 NO-1 NC contact set provides precise trip signaling and seamless integration with centralized control logic, supporting clear status feedback to supervisory systems. Its fusible protection and 600 VAC / 250 VDC capability offer flexible protection schemes across mixed-voltage installations, lowering the need for additional interposing devices and reducing lifecycle costs. The NEMA 12 and NEMA 3R enclosures protect against dust, moisture, and weather, simplifying installation in challenging environments. In addition, the integrated alarm switch enables proactive monitoring and faster response to fault conditions. UL Listed and cUL Certified markings give procurement teams regulatory confidence for global deployments. Warranty terms align with Eaton Policy, reducing risk during early-life operation. This device is well-suited for industrial protection devices and safety switches in automation facilities, delivering measurable gains in safety, uptime, and compliance.

FAQs
STS367ND11 is a three-pole shunt trip safety switch with a 24 VAC coil and 1 NO-1 NC configuration, designed for motor control centers and switchgear. Its NEMA 12 / NEMA 3R enclosure simplifies mounting in dusty, damp, or outdoor environments, while maintaining straightforward wiring to existing control circuits.
The device supports up to 800 A with a 600 VAC / 250 VDC rating and an integrated alarm switch. The contact configuration is 1 NO-1 NC, ideal for signaling and fail-safe shutdown, with a 24 VAC coil driving the trip mechanism for reliable operation in standard control circuits.
Yes. With fusible protection and a broad voltage rating of 600 VAC and 250 VDC, the unit can coordinate with upstream protective devices in mixed-voltage distributions. This reduces the need for additional components and helps achieve coordinated protection in complex plant layouts.
STS367ND11 carries UL Listed and cUL Certified markings, supporting global procurement. These certifications help with regulatory audits, quality assurance, and safety program alignment in industrial environments such as manufacturing, process industries, and critical infrastructure.
The integrated protection features, alarm signaling, and standardized 24 VAC control simplify maintenance and monitoring. A single, clearly labeled safety switch reduces stocking and training needs, while Eaton warranty terms provide assurance during early operation, contributing to lower total cost of ownership in long-running industrial systems.
