  • Safety first
    Highly-visible ON/OFF label and coin-proof integral interlock reduces potential for error and tampering. Easy-grip, hook-stick-operable red handle accepts three padlocks in OFF position. Clear line shield on 30 to 200 A models reveals blade position while helping to prevent contact with live parts. Optional viewing windows allow a visual confirmation of both the contact blade position and fuse status.
  • Long, reliable service life
    Quick-make-and-break mechanism and plated contacts offer durability. Spring-reinforced fuse clips assure reliable contact for cool operation. Powder-coat finish and galvanized steel for outdoor enclosures resist corrosion.

  • Save installation time
    Three-point mounting speeds installation. Wide, unobstructed gutter eases wire pulling and connection. Cu/Al lugs rated 60/75 °C allow greater wire selection. Standard factory installed neutrals at 240V and optional factory-installed neutrals at 600V in 30 to 200 A switches saves installation time and prevents the neutral from being forgotten or misplaced.
