Disconnect switches

Ferraz Shawmut's Sirco and Fuserbloc 600 Vac/250 Vdc fusible and non-fusible switches feature make-and-break power circuits under load and are UL, CSA, CE, and IEC-rated.

Features & benefits

  • Sirco available in 30 to 800 A ratings; those to 400 A come with visible blade contacts

  • Fuserbloc break up to 200 A and use double break contacts per pole, isolating fuse while switch is off

  • Available handles meet OSHA padlocking needs, NEMA configurations, defeater options, and NFPA 79

  • Work independently of speed and force of operator

  • Switches to 400 A use silver-tipped contact technology for high load breaks and long life; switches more than 400 A use self-cleaning technology for high short-circuit resistance
