FAQs
Install the STS367UD61 as a non-fusible, three-pole device within a compliant motor control center or switchgear. Wire the 24 Vdc coil to the control circuit, connect the 1NO 1NC contacts for status/interlock signaling, and ensure the enclosure is aligned with the NEMA 12 or NEMA 3R environment. Follow manufacturer wiring diagrams for proper clearance and torque specs.
The STS367UD61 is rated for 800 A and supports 600 Vac / 250 Vdc, with a 24 Vdc coil. It features a 1 NO 1 NC contact configuration and a non-fusible design, making the device suitable for direct protection and signaling in high-current circuits while enabling straightforward control logic integration.
Yes. With a three-pole configuration and non-fusible protection, it provides reliable, fast disconnection for MCCs. Its NEMA 12 and NEMA 3R enclosures offer protection against dust, moisture, and varying environmental conditions, making it well-suited for industrial floors, outdoor installations, and process lines requiring robust safety interlocks.
The STS367UD61 carries UL Listed and cUL Certified marks, signaling compliance with widely recognized safety standards. These certifications simplify supplier qualification, reduce regulatory risk, and support safe integration into regulated facilities, especially in sectors with rigorous electrical protection requirements and commissioning standards.
Its non-fusible design reduces fuse-related maintenance and part replacements, while the robust enclosure ratings limit environmental degradation. UL/cUL certification supports ongoing compliance audits, and 800 A capacity paired with a 24 Vdc coil enables predictable performance and lower risk of unintended trips, contributing to higher uptime and lower lifecycle costs.
