AC Manual Motor Starting Switches
Specifications and Features
Motor Starting Switches
• All molded parts are thermoplastic to resist impacts, chemicals, temperature, tracking and arcing
• 30 Amp and 40 Amp switches are listed suiitable as motor disconnect when protected by a 30 Amp time-delay fuse
• Positive-contact design enhances fast-make/slow-break
• Silver-alloy contacts for maximum conductivity and service life
• Back and side wire terminals accept up to #10 AWG solid copper wire. For stranded #8 AWG wire, remove terminal
clamp and use ring terminal (sold separately)
• Oversized #10 triple-combination terminal screws are vibration resistant
• Insulating barrier between terminals provide isolation from each phase
• Nickel-plated brass mounting yoke for superior corrosion resistance
• Large toggle provides positive actuation, even with gloved hand
• Backed by a Limited Ten-Year Warranty
Welding Starting Switch
