Why this product matters Eliminates the need for an external power source: the selfoperated design reduces wiring, installation time, and dependence on separate supplies. Works across a wide range of AC loads: adjustable action current from 0.2 A to 30 A AC lets one device cover small to moderately large circuits without swapping parts. Simple, ondevice control and feedback: a potentiometer lets you set the trip/activation current precisely; an LED status indicator makes operation and troubleshooting visible at a glance. Built for dependable switching: uses performance plaster tube technology for a SIN to improve switching stability and response. Key functions and attributes Function: selfpowered currentactuated switch with adjustable trip/current action. Compatibility: designed for AC circuits and loads within the 0.2 A to 30 A adjustable action range. Control: potentiometer for fine adjustment of action current. Status indication: LED indicator for monitoring switch state and operation. Performance: performance plaster tube technology for a SIN to support reliable switching behavior. Installation: selfoperated unit reduces external wiring and eliminates separate power supply requirements. How it solves common problems Reduces installation complexity and cost by removing the need for separate power wiring. Replaces multiple fixedthreshold devices by covering a broad 0.2–30 A range with a single adjustable unit. Improves uptime and maintenance speed with visible LED status feedback for quick diagnostics. Enhances switching consistency through the plaster tube technology for a SIN, helping prevent nuisance trips and unreliable actuation. Typical use scenarios 1. Motor protection and control: set the action current to match small AC motors or pump starters to protect against overcurrent or to automate on/off control without extra supply wiring. 2. Lighting and appliance circuits: use the adjustable trip range to automate or protect lighting banks and AC appliances that draw from 0.2 A up to 30 A. 3. Industrial or equipment panels: integrate as a compact, selfpowered currentactuated switch in control panels where visible status (LED) and a wide adjustable current range simplify inventory and deployment. Quick technical summary Action current: adjustable from 0.2 A to 30 A AC via potentiometer. Power: selfoperated (no external power supply required). Indicator: LED status indicator for switch operation. Technology: performance plaster tube technology for a SIN. Notes for selection and installation Verify expected operating current falls within the 0.2–30 A adjustable range. Use the potentiometer to set the exact activation threshold required by the load. Observe LED status during commissioning to confirm correct operation.
