FAQs
Install STS367ND64 in a panel or MCC with an 800 A rating, then wire the three-pole connections per the Eaton datasheet. Connect the 24 Vdc coil to the control circuit, and wire the 1 NO 1 NC auxiliary contact for status signaling to the PLC or safety interlock. Ensure proper fusible protection and correct labeling for safe operation.
Key ratings include 800 A amperage, 600 Vac and 250 Vdc voltage ratings, and a 24 Vdc coil. It is a three-pole shunt trip with a 1 NO 1 NC auxiliary contact and is designed for fusible applications, with NEMA 12 and NEMA 3R enclosures for versatile installation.
Yes. Its three-pole configuration and 800 A capability are well suited for MCCs and heavy-duty panels requiring robust fault protection. The 24 Vdc coil enables easy PLC/safety interlock integration, and the NEMA 12/3R enclosures provide indoor and semi-outdoor mounting flexibility for industrial environments.
STS367ND64 carries UL Listed and cUL Certified marks, simplifying regulatory approvals for end users and OEMs. These certifications support safety compliance, documentation, and supplier qualification, while the device’s fusible protection and defined voltage ratings help ensure reliable shutdown behavior in regulated industrial settings.
Eaton’s policy 25-000 provides a one-year warranty from installation or eighteen months from shipment, whichever comes first. This coverage, along with Eaton’s support resources and datasheets, offers predictable maintenance planning and helps protect your project’s ROI over the equipment lifecycle.
