Overview
The Square D GV2G05 is a professional-grade terminal block from the TeSys GV series by Schneider Electric. This component is engineered to serve as a power distribution interface for modular motor starter and contactor systems. It supports three-phase circuits with screw clamp terminal connections, providing reliable power distribution for industrial automation and motor control applications.

Typical Applications
The Square D GV2G05 terminal block is commonly used in:
- Motor control centers (MCCs) — as input distribution blocks for multi-motor starter panels
- Industrial machinery — providing power feed to pump motors, fan drives, and conveyor systems
- HVAC systems — distributing three-phase power to large motor loads
- Process automation — feeding power to TeSys D/K/U contactor arrays in modular control schemes
- Manufacturing environments — where DIN rail–mounted power distribution simplifies panel layout and troubleshooting
