Overview
The Square D GV2-G05 is a TeSys GV terminal block designed for multi-motor installations requiring parallel motor starter connections. Rated 63A at 690V AC (600V maximum in North American applications), this 3-phase component is a key accessory in distributed motor control systems. Manufactured by Schneider Electric (Telemecanique brand), the GV2-G05 simplifies busbar distribution and reduces wiring complexity in panel or DIN rail installations.
Key Features
- 3-phase configuration with 63A current rating
