The Schneider Electric GV2P03AE11 is a 3-pole motor circuit breaker from the TeSys GV2 series, rated at 0.4 A and designed for motor protection in industrial control panels. It combines a thermal-magnetic trip unit with a rotary handle for manual control and isolation. The 0.4 A rating protects a 0.09 kW motor at 400/415 V AC, making it suited for small fractional-horsepower loads like fans, pumps, or conveyors in light-duty applications.
Breaking capacity is 100 kA Icu at 400/415 V AC, which means it can safely interrupt a fault current up to 100,000 A without failing. The thermal-magnetic trip provides overload protection via a bimetal strip and short-circuit protection via a magnetic coil. The magnetic trip threshold is fixed at 5.8 A, so it clears hard faults fast while letting motor inrush pass. Phase failure sensitivity is built in per IEC 60947-4-1, so the breaker trips if one phase drops out — critical for preventing single-phasing damage on three-phase motors.
IP20 finger-safe protection means it's suitable for enclosed panels where no washdown or dust ingress is expected. The IK04 impact rating handles incidental tool contact during commissioning. Power dissipation is 2.5 W per pole, so three poles total 7.5 W at rated current. Factor that into cabinet thermal calculations to avoid derating in a sealed enclosure.
Approvals include UL 60947-4-1, CSA C22.2 No 60947-4-1, and EN/IEC 60947-2 and 60947-4-1, so it is accepted in North American and European panels without additional certification work.
