The Square D GV2RS07 is a GV2-RS07 manual motor starter rated 600VAC at 2.5A per IEC. It's a current-production part in the GV2 family, which means it's still a standard catalog line — no phase-out notice to chase down for a BOM line.
For a 400V three-phase motor, that maps to roughly a 1.1 kW load — small pumps, fans, or conveyors. The 600VAC maximum is the insulation voltage rating, not the motor voltage; the actual motor voltage is whatever the coil and overload block are configured for, typically 230V or 400V on these GV2 frames.
