Product Bulletin for 30 Amp and 40 Amp Motor Starter Switches Industrial Grade Manual Motor Controllers Suitable as Motor Disconnect 30A and 40A Motor Starter Switches for Single Phase and Three Phase Applications Leviton s line of industrial grade AC Manual Motor Controllers provide safe, reliable control of a variety of motor loads. Typical applications include manual ON/OFF switching control of bottling lines, pumping machines, air compressors and other heavy manufacturing equipment. These Motor Controllers are available for both single-phase and three-phase applications, with a continuous current rating at all voltages up to 600V AC and maximum horsepower ratings of 20HP. In addition, they are listed UL 508 Suitable as Motor Disconnect. This also provides for lowering facility costs (when compared to installation of UL98 Disconnect Switches). Features include: All molded parts are thermoplastic to resist impact, chemicals, temperature, tracking and arcing Cam-driven mechanism enhances fast-make/slow-break Silver- Alloy contacts for maximum conductivity and service life External clamps accept back and side wiring Insulating barrier between terminals provide isolation between phases Nickel-plated brass mounting yoke for superior strength and corrosion resistance Oversized toggle provides positive actuation, even with gloved hand Backed by a Limited Ten-Year Warranty Leviton Manual Motor Controllers are available as either single switches or with enclosures. Available enclosures include Type 1 Thermoplastic, Type 1 Powder-Coated Metal, or Type 3R Powder-Coated Metal.
AC Manual Motor Controller Features Oversized PBT toggle is capable of withstanding extreme impact, harsh chemical attack, and prolonged ultraviolet exposure Mounting yoke is permanently marked with catalog number, amperage, voltage and horsepower ratings for easy identification Oversized toggle is easy to turn ON/OFF with gloved hand Nickel-plated, brass mounting yoke offers exceptional strength and corrosion resistance Nickel-plated brass bushings secure yoke to device Internal chamber barriers prevent flash-over between phases #10 triple-drive nickel-plated terminal screws facilitate tightening to proper torque ranges Impact-resistant PBT cover and base External clamps accept back and side wiring for #10AWG solid copper wire.
