Current Switches What this product does Monitors electrical current on a conductor and provides a switching output when a preset threshold is reached. Converts current level into a reliable on/off signal for control circuits, relays, PLCs, alarms, or protective devices. Key benefits Protect equipment and processes by detecting overcurrent or loss-of-load conditions quickly and reliably. Simplify control logic by producing a clean switching output that integrates with standard control systems. Reduce unscheduled downtime and maintenance by enabling automated responses to abnormal current conditions. Important attributes Function: Current monitoring and threshold-based switching; provides a discrete electrical output when the monitored current crosses the setpoint. Compatibility: Designed to interface with common control equipment (relays, PLC digital inputs, alarm circuits). Suitable for use with typical single-phase and three-phase conductors when appropriately applied. Size and mounting: Compact form factor for panel or DIN-rail installation; intended to fit standard industrial enclosures and control cabinets. Material and durability: Housings and terminals designed for industrial use to withstand normal shop and plant environments. Performance: Fast, repeatable switching action for reliable detection of overcurrent, undercurrent, or phase-specific conditions as applicable to the chosen model. Practical applications (use scenarios) Motor protection and control: Detect motor stall or sustained overcurrent and send a trip or warning signal to protect the motor and driven equipment. Process and machine monitoring: Trigger alarms or shut down sequences when conveyor or pump current falls outside normal ranges, indicating jams, blockages, or no-load conditions. Panel and generator management: Provide load-sensing inputs for load-shedding logic, generator control, or remote monitoring to prevent overloads and coordinate protective actions. Why choose a current switch Straightforward integration: Provides a single-purpose, focused signal for existing control and protection systems without complex setup. Versatile application: Useful across industrial, commercial, and utility environments where current-based control or indication is required. Dependable operation: Designed for continuous monitoring with consistent switching behavior under normal operating conditions. Installation and use tips Select the appropriate model for the conductor size and current range of your application. Follow recommended wiring practices and mounting orientation shown in the product documentation. Verify compatibility of the switch output with the input requirements of your control device (voltage/current levels, contact type). Available options and selection guidance Choose between models offering fixed or adjustable trip thresholds, and between different output types (mechanical relay, solid-state, open-collector, etc.) according to control system requirements. Confirm physical mounting and terminal arrangements to match your control panel layout. Safety and compliance Use as part of a properly designed control or protection scheme. Follow electrical codes and manufacturer instructions during selection and installation. For detailed model selection, installation diagrams, and performance specifications, consult the product datasheet or technical support resources associated with the specific current switch model you plan to install.
