High-current capability and fusible protection: The STS367FW64 delivers 800 A, providing robust protection for high-load feeders, reducing the risk of cascading faults and downtime, and enabling safer startup sequences in heavy electrical loops. This translates to lower maintenance costs and improved plant availability in critical process lines. Three-pole design and 1 NO 1 NC: Reliable trip logic supports coordinated protection across multi-pole feeders and simplifies wiring to safety relays or PLCs, enhancing diagnostics and reducing commissioning time during panel rebuilds. Voltage flexibility: With 600 Vac / 250 Vdc ratings and a 24 Vdc coil, the switch accommodates mixed AC/DC environments and downstream control circuits, improving site-wide compatibility and reducing stock diversity. Rugged enclosure: The NEMA 4X, 304 stainless steel housing delivers corrosion and weather resistance for outdoor or washdown areas, extending service life in demanding facilities and lowering total cost of ownership. Alarm signaling and auxiliary contacts: The 1 NO 1 NC auxiliary contact enables seamless integration with safety PLCs and annunciation systems, supporting proactive fault monitoring and faster response times. Compliance and documentation: UL Listed and cUL Certified credentials simplify regulatory approvals across North America and international sites, facilitating global deployment and standardized maintenance routines. Mounting and footprint considerations: With a length of 12.43 in, height of 71.72 in, width of 29.54 in, and weight of 167 lb, planners can accurately allocate panel space and plan for safe handling during installation.
