Current Switches What it does Detects electrical current and provides a switching signal when a preset threshold is reached. Used to trigger alarms, interlocks, or control devices without continuous monitoring. Key benefits Protect equipment: Detects overcurrent/undercurrent conditions to prevent motor stalls, pump run-dry, or other harmful states. Simplifies automation: Converts analog current into a clear on/off signal compatible with relays, contactors, and PLC inputs. Reduces downtime: Early fault detection and automatic shutoff or alarm initiation minimize damage and service interruptions. Easy integration: Designed for straightforward panel or cabinet installation and straightforward wiring into existing control systems. Important attributes Function: Monitors line current and closes or opens a contact (or provides an electronic switching output) at a user-set threshold for reliable trip signalling. Compatibility: Interfaces with standard control equipment such as relays, contactors, PLCs, and alarm systems; suitable for use with common AC or DC circuits depending on model. Size & mounting: Compact profile for panel- or DIN-rail-friendly installation, enabling space-efficient retrofits and new panels. Material & build: Industrial-grade housing and components configured for stable operation in typical electrical environments. Performance: Provides repeatable, fast switching at setpoints with stable behavior under sustained loads; adjustable setpoint and reset options support different application needs. Practical applications Motor protection: Detects stall or overload conditions and signals a contactor or PLC to shut down or initiate a controlled stop. Pump and fan monitoring: Detects loss of flow or blocked impellers indicated by undercurrent/overcurrent and triggers alarms or shutdowns to prevent damage. Process automation and energy management: Provides discrete current status to control logic for sequencing, equipment interlocks, or energy-use monitoring. Installation and use Simple mounting and wiring into existing control circuits; set trip threshold to match protection or control requirements. Select the appropriate model for the circuit type (AC or DC) and desired output style (dry contact or electronic interface). Reliable, space-efficient, and practical for panel-level protection and control tasks where a clear, repeatable current-based switching signal is required.
