The 400A amperage rating and three-pole, three-wire configuration provide robust protection for large-motor feeds while supporting 240V circuits, reducing arc-flash risk and enabling compliant lockout/tagout procedures in line with industry standards. The NEMA 4 painted steel enclosure offers weather and corrosion resistance, enabling reliable outdoor or washdown installations with minimal enclosure maintenance and long service life. Fuse class provision Class H and a fusible without neutral setup simplify retrofits and new installs by aligning with common protection strategies for motors and feeders up to 50 HP per standard, or up to 125 HP/50 HP for DC conditions, supporting a broad range of industrial loads. Enhanced visible blade design improves operator visibility during operation and maintenance, reducing misoperation and improving safety during panel clearance. The compact footprint of 64.5 in length, 26 in width, and 13 in height helps optimize panel real estate while the unit weight of 123 lb supports crane or cart-based installation in tight spaces. UL Listed certification reinforces compliance with electrical safety standards, giving maintenance teams confidence in routine inspections and regulatory audits. This switch is well-suited for motor control centers, process lines, and packaging equipment where rapid, safe isolation and durable protection are essential for uptime and reliability.

FAQs
For safe mounting, ensure a reinforced panel frame supports a 123 lb enclosure with dimensions of 64.5 in length, 26 in width, and 13 in height. Provide adequate clearance for three-pole wiring and fuse access, use the specified conductor sizes (2) #1/0 to (2) 300 kcmil or (1) #1/0 to (1) 750 kcmil Cu/Al, and observe 240V operation with a 400A rating. Follow lockout/tagout procedures and maintain the NEMA 4 protection in outdoor or damp environments.
The 400A rating, three-pole design, and 240V applicability make it ideal for feeding large motors and MCC sections. With a HP max of 50 and 125/50 hp for DC configurations, it accommodates a wide range of industrial motors. The UL Listed, NEMA 4 enclosure provides reliable protection in harsh environments, reducing unplanned downtime and protecting personnel during maintenance.
This safety switch is UL Listed, signaling compliance with recognized electrical safety standards. It also uses a NEMA 4 enclosure, ensuring suitability for wet, dusty, and outdoor environments. These certifications help meet regulatory requirements, simplify audits, and provide peace of mind for installers, maintenance teams, and end users regarding long-term reliability and safety.
Yes. The device features fuse configuration Fusible without neutral and a fuse class provision of Class H. It supports conductor ranges of (2) #1/0–(2) 300 kcmil or (1) #1/0–(1) 750 kcmil copper or aluminum. This flexibility simplifies integration with existing protection schemes and allows tuning for motor and feeder protection while maintaining safe isolation.
The robust NEMA 4 enclosure, UL Listing, and durable painted steel construction lower corrosion risk and reduce maintenance frequency in harsh environments. The clear isolation path and enhanced blade visibility speed service and tests, minimizing downtime. Overall, it delivers safer operation, better uptime, and predictable life-cycle costs for panels, MCCs, and industrial equipment.
