The Schneider GV3L40 is a 40 A motor circuit breaker from the TeSys Deca range, rated for motor protection with a magnetic trip set at 560 A and a breaking capacity of 100 kA at 230/240 V AC. That 40 A line current matches the full-load amps of a motor up to 18.5 kW at 400 V or 22 kW at 500 V — the power figures you care about for BOM matching. The magnetic trip at 560 A is instantaneous; it clears a bolted fault before the motor's thermal curve sees it, so you size the breaker so that trip is above the motor's starting inrush (typically 6–8× FLA). With 50 kA Icu at 400/415 V and 12 kA at 500 V, this breaker handles most industrial panel SCCR requirements without an upstream current-limiting fuse.
The rotary handle gives a clear on/off indication at the panel door — isolation suitability is marked per IEC 60947-1. Coil draw isn't an issue here since it's a thermal-magnetic breaker, not a contactor; the 8 W power dissipation per pole needs a little air movement if you pack several in a row. Wiring: screw-clamp terminals torque to 5 N·m, accepting conductors up to the rating. The IP20 means it's for enclosure use, not washdown.
Compliance documentation covers EN/IEC 60947-2 and -4-1, UL 60947-4-1, and CSA C22.2 No 60947-4-1. Fire resistance tested to 960 °C (IEC 60695-2-11). Climatic withstand per IACS. Storage temperature range -40 to 80 °C. These make it viable for machinery exports to North America and Europe without separate qualification runs.
