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.
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 Controllers “Suitable as Motor Disconnect”30A and 40A Motor Starter Switches for Single Phase and Three Phase Applications
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).
