Insulator Profile: Parallel or Vee Configuration

Current: 600, 1200, and 2000 Ampere

Description
A three insulator, group operated, side-opening, air-break disconnect switch, with a single center rotating insulator per phase for operation. 

Application
Comparable to a vertical break and often used as a substitute where there are overhead clearance problems.  Has the same phase spacing requirements as a vertical break.  

Frequently used for line disconnecting, isolating and by-passing breakers and transformers, bus sectionalizing, and isolating arrestors, metering equipment, and other apparatus.  Can be either pole or substation structure mounted.  

Features & Benefits
Minimal phase spacing reduces structure size and weight

Excellent ice breaking characteristics

Horizontal break minimizes overhead clearance issues

Horizontal break aligns with substation bus in low profile substations to maintain desired appearance

Lower cost compared to vertical breaks
