FAQs
STS367UP6 is designed for standard three-pole protection with a NEMA 4 painted steel enclosure, ideal for indoor and outdoor plant environments. Its dimensions support retrofit in common electrical spaces, and its weight supports secure, robust mounting in control panels and MCCs. Ensure mounting provisions match the enclosure footprint and allow for proper cable entry and coil access.
The device uses a 24 Vdc coil to produce a magnetic trip when a control signal is applied. This allows a remote trip command from safety interlocks or a plant-wide safety system, providing fast, reliable disconnection of the 800 A circuit at 600 Vac / 250 Vdc ratings while remaining compatible with common control circuits.
Yes. STS367UP6 is rated for 600 Vac and 250 Vdc, supporting non-fusible operation in three-pole configurations. This makes it suitable for high-energy motor control centers and switchgear, enabling safe, code-compliant shutdown during fault or safety-trip scenarios.
The STS367UP6 carries UL Listed and cUL certifications, signaling compliance with safety and performance standards for electrical protection devices. These certifications simplify procurement for regulated facilities, support audit readiness, and help ensure reliable operation in industrial environments where safety and compliance are paramount.
The non-fusible design reduces fuse-related maintenance, while UL/cUL certification and NEMA 4 enclosure improve reliability and uptime. Although the unit is heavy, its robust construction lowers field service frequency and replacement risk. Over a typical lifecycle, this translates to improved safety, fewer unplanned outages, and predictable maintenance budgeting.
