The CA10 3Position 3Phase Rotary Cam Changeover Switch is a compact, mechanical switch designed to route threephase power through a single rotary action. Its cam driven mechanism provides synchronized switching of all three phases, enabling reliable changeover between three circuit paths in control panels, equipment enclosures, and other electrical assemblies. Key benefits Enables quick and straightforward manual changeover in threephase systems, reducing downtime and simplifying wiring. Synchronised switching across all three phases improves reliability and minimizes the risk of crossconnection or phase misalignment. Durable, lowmaintenance design suited to regular operation in control panels and industrial environments. Positive tactile feedback and stable detents help operators confirm switch position during operation. Compact form factor supports installation in standard panel openings and constrained spaces. Key attributes Functionality Provides 3position rotary cam changeover for threephase circuits, allowing the common connection to be routed to one of three outputs. Cam operated for consistent contact timing and repeatable operation across switching cycles. Compatibility Designed for use in standard electrical control panels and equipment housings that require threephase changeover. Suited for integration with common wiring practices for threephase distribution and control applications. Mounting and shaft configurations aligned with typical panel and enclosure installations to facilitate installation and maintenance. Size Compact form factor suitable for panel mounting in spaces where space is at a . Sized to fit standard cutouts and mounting arrangements found in many control panel designs. Material Built with a durable housing and robust internal components to withstand regular operation. Contact materials and internal components selected to provide dependable electrical performance and long life (details vary by model and production batch). Performance Designed for reliable, repeatable operation across multiple switching cycles. Engineered to maintain good electrical contact and minimize wear during normal use. Suitable for threephase control applications requiring coordinated switching of all three conductors. Two to three common use cases Power source changeover for a threephase motor: Use the CA10 to switch a motor's threephase supply between multiple power sources or feeders, enabling quick transitions without rewiring. Threephase circuit routing in a control panel: Route the three phases to different load circuits or distribution feeders within a panel, allowing easy reconfiguration for testing or maintenance. Test bench or lab switching: In a laboratory or test environment, swap threephase loads between different test circuits or sources with a single rotary action for efficient experimentation and setup.
