Feature: The STS367FD6 delivers an 800 A amperage rating and fusible protection, enabling reliable interruption of heavy-duty circuits without nuisance tripping. Business impact: This reduces equipment damage, extends motor life, and lowers downtime costs by delivering decisive protective action during faults. Application: Ideal for three-phase motor control centers and high-load conveyor systems where robust fault isolation is essential. Feature: A 24 Vdc coil voltage provides direct compatibility with common PLC outputs and control circuits. Business impact: It simplifies control wiring, reduces integration risk, and speeds installation. Application: Suitable for plant-wide safety interlocks and remote shutdown schemes in automation panels. Feature: Voltage ratings of 600 Vac and 250 Vdc support multi‑rail systems. Business impact: Allows a single device to protect both AC power and DC control paths, reducing part counts and inventory. Application: Panels that service mixed-voltage machinery and safety circuits. Feature: NEMA 12 and NEMA 3R enclosures offer environments protection. Business impact: With weather and dust resistance, maintenance windows widen and corrosion is mitigated. Application: Outdoor enclosures, dusty manufacturing floors, and service areas where harsh conditions exist. Feature: Three-pole construction ensures simultaneous interruption of all conductors. Business impact: Improves safety by guaranteeing complete shutdown of the circuit in fault events. Application: Standard three‑phase power distribution and motor starter assemblies. Feature: Certifications and warranty provide assurance; also the 1-year warranty policy. Application: Safety-driven installations with risk-managed maintenance planning and predictable life cycle costs.

FAQs
Plan installation in a compatible NEMA 12/3R enclosure and mount the three-pole device in a serviceable panel. Wire the 24 Vdc coil to a properly fused control circuit, observe clearance for the enclosure, and follow UL/cUL guidelines. Ensure fault-path wiring allows remote shutdown via PLC or safety interlock outputs and verify conformity with the 600 Vac/250 Vdc ratings.
Yes. The STS367FD6 uses a 24 Vdc coil, designed for direct interfacing with standard PLC outputs and control circuits. Use appropriate isolation and interlock wiring, and select proper fusing and protective devices to maintain coil integrity and safe operation within your control architecture.
Ideal for industrial motor control centers, safety interlocks on conveyors, and machine protection in harsh environments. The 800 A rating supports high-current loads, while the NEMA 12/3R enclosure provides dust and moisture resistance, making it suitable for both indoor factory floors and outdoor or rugged service areas.
The STS367FD6 is UL Listed and cUL Certified, ensuring compliance with common electrical safety standards. It features a three-pole design in a NEMA 12/3R enclosure, with a 600 Vac / 250 Vdc rating, and a 24 Vdc coil, aligning with typical industrial protection and control panel requirements.
This switch provides rapid fault isolation, reducing downtime and limiting equipment damage in fault events. It supports easier panel commissioning with standard control interfaces, and its UL/cUL certification simplifies compliance audits. A one-year warranty (18 months from shipment) offers predictable maintenance planning and total cost of ownership improvements.
