Type: 3G (airbreak) and 3GL (loadbreak)
Orientation: Phase-Over-Phase
Voltage: 15 - 230 KV

Current: 600, 1200, 2000 and 3000 Ampere

Description
Side-break style switch in a phase-over-phase configuration, with horizontal upright mounting on an aluminum support structure.  Three individual switch pole units are arranged in an integral design, sharing insulators, interrupters, and other switch components.   Provides switching for both alternate sources and the tap line.

Application
Three-way switches are frequently used for line taps, ties, and sectionalizing. Phase-over-phase arrangements are especially helpful where restricted right-of-way or difficult terrain make other switch/structure configurations unworkable.

Features & Benefits
Small footprint minimizes right-of-way requirement

Excellent ice-breaking characteristics

Reduces construction costs and time vs other switch configurations

Clean visual appearance, less objections from communities

Provides design flexibility to system designers
