Product overview A compact soft switch current limiter designed for 230V mains to control inrush and starting current for power tools that draw between 12 and 20A. The unit provides a controlled, gradual motor startup to reduce stress on the motor, switch, and electrical circuit while keeping installation simple and inline with existing tooling. Key benefits Reduces inrush and starting shocks that can cause circuit breaker trips or nuisance fuse blows when starting torque tools. Smooth motor ramp up extends the working life of motors and mechanical components by reducing mechanical stress at startup. Improves operational stability when using long extension cables or marginal supply circuits by limiting peak current draw. Simple inline solution that works with a wide range of 12 to 20A power tools without modifying the tool itself. Main features and specifications Input voltage: 230V AC. Rated load range: suitable for tools drawing 12 to 20A. Function: soft switch current limiter providing soft start and current limiting during motor startup. Application: intended for use with angle grinders and other handheld or stationary power tools within the specified current range. Design: compact inline module suitable for workshop and jobsite use. Compatibility and use Works with angle grinders, circular saws, bench grinders, routers, and similar power tools that normally draw 12 to 20A on a 230V supply. Intended for inline use between the mains supply and the tool, positioned before the tool power switch. Practical use scenarios 1) Jobsite with limited circuit capacity: Use the limiter when starting an angle grinder from a circuit shared by lighting or other tools to reduce the chance of tripping circuit protection during tool startup. 2) Long extension lead or remote power source: Install inline to control peak current caused by voltage drop on long leads, helping the tool start smoothly and maintain performance. 3) Older or inrush tools: Fit the unit to older grinders or saws to reduce mechanical stress and achieve gentler starts during routine operations. Installation and handling Install inline between the mains supply and the tool input, before the tool switch. For permanent installations or if you are unsure about wiring, consult a qualified electrician. Designed for retrofit to existing tools without internal modification. Why choose this unit This soft switch current limiter provides a straightforward, compact way to manage startup current for tools that draw 12 to 20A on 230V supply. It minimizes startup impacts on electrical circuits and tool components while remaining broadly compatible with common power tools used in workshops and on jobsites.
