FAQs
The unit is a three-pole, fusible switch with fusible without neutral configuration. Use #14-1/0 AWG conductors rated for 600 V, and mount within a NEMA 12 / NEMA 3R enclosure. Ensure accessible line and load terminals, maintain proper clearance for maintenance, and apply lockout/tagout procedures during servicing. Verify UL Listed compliance in your panel design.
Key ratings are 100 A amperage, 600 V voltage, and Class H fuse provision. The device is designed for 30, 40/60, and 75 hp loads (1/3 PH at 480/600 V), enabling effective protection for mid-size motors. The fusible without neutral configuration simplifies wiring and enhances short-circuit protection while maintaining safe, predictable disconnection behavior.
Industries with motor-driven processes and distributed power needs—such as manufacturing, packaging, material handling, and automated assembly—benefit from this switch. It fits motor control centers and electrical rooms requiring robust dust-tight and damp-environment protection (NEMA 12/3R), reliable lockout capability, and scalable protection for mid-range motor loads.
Yes, the device is UL Listed, a widely recognized safety certification for electrical equipment. It also features a NEMA 12 / NEMA 3R enclosure suitable for dust-tight and splash-prone environments, supporting safe operation in industrial facilities. This combination aligns with common electrical protection standards required for panel builders and end users.
Regular inspections focus on visual status indicators, terminal integrity, and enclosure cleanliness to prevent corrosion and arc-flash risk. The rugged galvanized steel enclosure reduces corrosion-related downtime, while the built-in line/load indicators speed fault localization. Over time, this translates to lower maintenance labor, shorter downtime, and improved process uptime for mission-critical equipment.
