The Schneider Electric TeSys GV2P21AE11TQ is a 3-pole motor circuit breaker rated at 23 A, part of the TeSys Deca range. It uses a thermal-magnetic trip unit, meaning the thermal element protects against sustained overloads and the magnetic element handles short-circuit faults. The magnetic tripping current is set at 341 A, so it clears fast on high faults without nuisance tripping on motor inrush.
Breaking capacity and fault handling
Rated breaking capacity (Icu) reaches 100 kA at 230/240 V AC, 50 kA at 400/415 V, and 20 kA at 440 V, all per IEC 60947-2. At the motor's common 400 V supply, 50 kA is high enough for most industrial panels with a transformer-fed fault level.
Motor protection specifics
Sized for motor loads: it switches 9 kW at 400/415 V, 11 kW at 500 V, and 18.5 kW at 690 V. The utilisation category includes AC-3 and AC-3e per IEC 60947-4-1, so it handles starting and stopping of squirrel-cage motors with occasional plugging or inching. Phase-failure sensitivity is built in, per IEC 60947-4-1, which protects a motor from single-phasing. Electrical durability is rated at 100,000 cycles at 415 V under AC-3 conditions.
Accepts power wiring via screw clamp terminals — up to two 6 mm² solid or 4 mm² flexible with ferrule. Tightening torque is 1.7 N·m. The front-mounted auxiliary contact block carries 1 NO + 1 NC, so you can wire a status feedback to the PLC without a separate contactor block.
IP20 rated, suitable for dry indoor panels. IK04 impact protection. Climatic withstand per IACS. Fire resistance tested to 960 °C per IEC 60695-2-11. Complies with EN/IEC 60947-2, EN/IEC 60947-4-1, UL 60947-4-1, CSA C22.2 No 60947-4-1, and IEC/EN 60335-2-40 Annex JJ. Suitable for isolation per IEC 60947-1.
