- Take the guesswork out of safety
Bright-red, lockable, three-position handle is easy to see and grip, and high-visibility ON/OFF/ON label reduces potential for operator error. Handle accepts three padlocks in OFF position.
- Long, reliable service life
Quick-make-and-break mechanisms offer reliable durability. Galvanized steel and stainless steel enclosures resist corrosion.
- Options to suit your applications and save cost
Available in 30 to 1200 A indoor and outdoor, 30 to 800 A stainless steel non-fused, and 30 to 400 A stainless steel fusible. 600 to 1200 A fusible models offer “stacked” design, using one common set of fuses for either source of incoming power — saving you money on fuses and reducing enclosure size for easier handling.
