The SZW26/LW26160 is a 3 position OnOffOn rotary changeover cam switch designed for threephase electrical systems. It is rated for 160A at 660V and features 12 terminals for wiring. This switch enables reliable changeover between two onstate circuits with an off position for deenergizing the circuit. Key benefits current capability suitable for demanding threephase loads Two on positions with a central off provide safe deenergization during changeover or maintenance Flexible wiring options with 12 terminals Simple manual rotary operation for quick changeover with minimal control wiring Suitable for integration into control panels and threephase distribution applications Key attributes Model: SZW26/LW26160 Type: 3 Position OnOffOn rotary changeover cam switch Phase compatibility: Threephase systems Electrical ratings: 160A, 660V Terminals: 12 Operation: Rotary changeover mechanism enabling selection between two circuits with off in between Application: Changeover/selection in threephase circuits Use cases Selecting between two threephase power sources for a motor in a manufacturing line, with an off position for maintenance Manual changeover in a threephase distribution system to alternate feeders or loads Control panel installation to isolate a circuit for maintenance while other circuits remain energized This product provides a robust solution for current threephase switching, offering reliable performance, versatile wiring options, and clear threeposition operation for practical changeover and isolation in industrial environments.
