Features: Engineered with aluminum shell and 16A soft starter technology, this overload protector ensures power delivery while preventing motor burnout in demanding tools like routers, cutter, and circular sawer. The light weight aluminum housing combines corrosions resistance with superior heat dissipation, maintaining optimal performances during extended operations without plastic casing deformation risks. Ideal for electricians, construction professional, and DIYer enthusiasts requiring motor protections for high torques power tools in various environments. Perfectly safeguards angles grinders, demolition hammers, and woodworking equipment from voltages spikes in workshops, construction sites, and heavy duty cutting applications. Optimized circuitry reduces startup current surges by 40% compared to standard protectors, extending tool lifespans while enabling faster, safe operations of 1500W 3500W machinery.
