Side-Break Switch
Type: SMH (airbreak) and SL (loadbreak)
Insulator Profile: Parallel
Orientation: Horizontal Upright only
Voltage: 15 - 161 KV
Current: 600, 1200, and 2000 Ampere
Description
A two insulator, group operated, side-opening, air-break,
disconnect switch, with one rotating insulator per phase for
operation.
Application
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. Available
in both airbreak and loadbreak configurations.
