Switch - 4-Phase, Switch is a rugged four-pole fusible switch engineered for reliable on/off isolation and overcurrent protection in demanding industrial and commercial environments. Its 4-Phase configuration provides complete disconnect of multi-conductor circuits, enabling safe maintenance and dependable operation in tough settings.
Designed as a compact, maintainable solution, this switch fits panelboards and switchgear where space is at a premium and accessibility for service is essential. It’s specifically ideal for motor disconnects, panelboards, and branch circuit protection, delivering robust protection in a single, integrated device.
When the handle is operated, all four poles switch together to either connect or disconnect the load. In the closed position, power is supplied to the protected circuit; in the open position, the circuit is safely isolated, with overcurrent protection ensured by the fusible design.
