FCSAW40333 - 400A, 240V, 3-Pole, Switch

Engineered for rugged reliability in demanding industrial and commercial environments, the FCSAW40333 is a 400A, 240V, 3-Pole fusible switch designed to deliver precise on/off isolation and overcurrent protection where it counts.

Its compact footprint and maintenance‑friendly design make it a practical choice for motor control and branch circuit protection. The three‑pole configuration ensures balanced disconnection of all phases, making it ideal for three‑phase motor disconnects, panelboard installations, and circuits that require reliable, centralized protection in a single enclosure.

• Three-pole isolation for every phase: Ensures complete shutdown of all conductors, reducing the risk of partial faults during service or maintenance.
• High current, low footprint: 400A capacity at 240V supports large motors, pumps, conveyors, and other high‑demand loads without enlarging the panel space.
• Integrated protection and isolation: Combines switching with overcurrent protection in one compact device, simplifying wiring and streamlining installation.
• Rugged, industrial-ready construction: Built to endure demanding environments, with a design that resists wear and repetitive operation.
• Versatile for critical power paths: A trusted solution for motor disconnects, panelboards, and branch circuits across manufacturing floors and commercial facilities.

Who should consider this switch? Facilities managers, electrical contractors, and OEMs responsible for heavy‑duty machines and power distribution. It’s well suited for manufacturing lines, HVAC systems, pumps, fans, and other three‑phase equipment where dependable isolation and protection are essential.

• Motor disconnects on production lines and machinery
• Panelboard protection and main/branch circuit isolation
• Three‑phase equipment in industrial and commercial settings
• Conveyor systems and processing equipment requiring reliable power control
