Current Switches What it does Detects conductor current and provides a reliable electrical output (relay, solidstate, or dry contact) when measured current crosses a set threshold. Enables monitoring and simple protective control without measuring exact amperage values. Key benefits — why you need it Protect equipment: trips or signals when motors, pumps, or circuits draw abnormal current, reducing risk of overload and downtime. Simplifies monitoring: provides clear on/off indication of load presence or overload conditions for control systems and operators. Low integration effort: interfaces directly with PLCs, relays, contactors, alarms, or indicator lights to add currentbased control without complex metering. Core attributes Function: Current detection and switching — opens or closes an output when current rises above or falls below the configured threshold. Compatibility: Designed to interface with common control and protection equipment (PLCs, relays, contactors, SCADA inputs). Suitable for AC and/or DC conductors depending on model. Size and mounting: Available in compact panelmount or DINrail/clipon formats for spaceconscious installations (select model as required). Material and construction: Rugged housing and electrical contacts designed for industrial and commercial environments; insulation and terminals comply with standard safety practices. Performance: Fast, repeatable switching response for reliable status signaling and protective action; consistent operation across normal industrial temperature and load conditions. Practical applications Motor protection: Detect stalled or overloaded motors by switching an alarm or tripping a control contact when current exceeds safe limits. HVAC and building systems: Monitor fans, compressors, and pumps; provide fault signals to building controls or service personnel when loads run or disappear. Production equipment monitoring: Track process machines and conveyors for unexpected load changes and integrate with PLC logic for automated shutdown or maintenance alerts. Installation and operation notes Select a model appropriate for conductor size, expected current range, and whether adjustable thresholds are required. Mount close to the monitored conductor for easier wiring; follow safety guidelines for isolation and grounding. Verify compatibility of the switch output type (relay, solidstate, dry contact) with the downstream control device before installation. Why choose a current switch A straightforward, costeffective way to convert current behavior into actionable control signals without full metering equipment. Proven solution for simple overload detection, loadpresent indication, and integration into automation and safety systems.
