The GV2RT03AE11TQ is a TeSys GV2 motor circuit breaker from Schneider Electric's TeSys Deca range, rated at 0.4 A continuous current (In) with a thermal-magnetic trip unit. That 0.4 A is the continuous rating that governs the motor protection curve — it's sized for a 0.06 kW motor at 230 V or 0.09 kW at 400 V, so the breaker's thermal element tracks the motor's heating characteristic, not just a generic branch circuit. The magnetic trip is set at 8 A, so the instantaneous short-circuit pickup is 20× the thermal rating. This is typical for motor-starting inrush. Breaking capacity is a flat 100 kA Icu across the voltage range from 230 V to 690 V AC, certified to IEC 60947-2.
The 78.5 mm depth leaves clearance in a standard enclosure. The front-mounted toggle provides manual on/off control and a trip-indicated position. The auxiliary contact block — 1 NO + 1 NC — is integrated into the front, so you get a remote status signal without an add-on module, useful for a PLC input or a seal-in circuit.
The 100 000-cycle electrical durability at AC-3 and AC-3e duty (at 415 V, full rated current) and matching mechanical endurance mean this breaker is rated for the life of a typical conveyor or pump motor in a production line — not a one-shot device.
Certified to EN/IEC 60947-2 (circuit-breaker standard) and EN/IEC 60947-4-1 (contactor-starter standard for motor protection), with suitability for isolation per IEC 60947-1. Climatic withstand conforms to IACS for marine environments, and the 960 °C glow-wire test per IEC 60695-2-11 covers fire resistance in the panel.
