Current Switches What it does Detects electrical current flow in a conductor and provides a simple switching output when a preset threshold is crossed. Converts current measurement into a reliable on/off signal for alarms, control inputs, or interlocks. Key benefits Prevents equipment damage by enabling fast detection of overcurrent, stalled motors, or unexpected load changes. Simplifies system integration by delivering a binary switching output compatible with PLCs, relays, and alarm circuits. Reduces downtime and maintenance effort by providing clear, repeatable trip indication without continuous monitoring. Why you need it Provides a low-cost, robust way to monitor circuits and trigger protective or control actions. Useful where continuous current measurement is unnecessary but automatic response to over or under-current conditions is required. Improves safety and asset protection with uncomplicated, dependable switching logic. Important attributes (general) Function: Monitors conductor current and changes output state when a setpoint is reached. Compatibility: Interfaces with standard industrial control systems, alarm panels, and auxiliary relays (check controller input type before installation). Size and mounting: Available in compact form factors suited to panel, DIN rail, or clamp-on installation (select the physical style that fits your installation). Material and durability: Built for electrical environments; choose versions with appropriate enclosure rating for your site. Performance: Provides repeatable switching action and stable thresholds; select a model with the response time and accuracy required for your application. Practical applications / use scenarios Motor protection: Detect a stalled or overloaded motor and send a stop or alarm signal to prevent damage. Control interlocks: Monitor feed or pump motors and interlock downstream equipment if current falls below or rises above a safe range. Energy and load monitoring: Trigger alerting or load-shedding when branch-circuit current exceeds planned limits. How to choose Verify the type of current to be monitored (AC or DC) and the conductor size or cable routing required for installation. Confirm the required trip threshold, output type (dry contact, solid-state, open-collector), and response speed to match your control system needs. Choose environmental protection and mounting style appropriate for panel, enclosure, or field use. Installation notes Install on the conductor according to manufacturer guidance to ensure accurate detection. Coordinate with upstream protective devices and control logic to avoid nuisance trips. Test switching function after installation to confirm correct setpoint and compatible interfacing. A current switch provides a straightforward, reliable way to turn current detection into actionable control or alarm signals — ideal for protecting equipment, simplifying monitoring, and automating safety responses.
