Typical applications include manual ON/OFFswitching control of bottling lines, pumping machines, air compressors and other heavymanufacturing equipment. These Motor Controllers are available for both single-phaseand three-phase applications, with a continuous current rating at all voltages up to 600VAC and maximum horsepower ratings of 20HP.

Leviton Manual Motor Controllers are available as either single switches or with enclosures. Available enclosuresinclude Type 1 Thermoplastic, Type 1 Powder-Coated Metal, or Type 3R Powder-Coated Metal.

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

Industrial Grade

Manual Motor ControllersSuitable as Motor Disconnect30A and 40A Motor Starter Switches forSingle Phase and Three Phase Applications

In addition, they are listed UL 508 Suitable as MotorDisconnect. This also provides for lowering facility costs(when compared to installation of UL98 Disconnect Switches).
