The Schneider Electric TeSys Deca GV2P22TQ is a 3-pole motor circuit breaker with a thermal-magnetic trip unit, rated at 25 A continuous current. It's sized for motor protection: 11 kW at 400/415 V AC or 15 kW at 500 V AC, both 50/60 Hz. Breaking capacity is the headline here — 100 kA Icu at 230/240 V, 50 kA at 400/415 V, and still 10 kA at 500 V. The part is certified to EN/IEC 60947-2 and 60947-4-1, plus UL 60947-4-1 and CSA C22.2 No 60947-4-1, so it passes both IEC and North American panel inspections. Phase-failure sensitivity is built in per IEC 60947-4-1 — if one phase drops on a motor load, the breaker trips on the thermal curve before single-phasing burns the winding.
The 45 mm width (three module spaces) fits standard enclosure cutouts. Depth is 97 mm, height 89 mm — check your gland plate clearance if back-panelling tight. Screw-clamp terminals accept up to 2 x 6 mm² solid or 2 x 4 mm² flexible with ferrule; torque to 1.7 N·m. IP20 finger-safe terminals, IK04 impact resistance. Rated for horizontal or vertical mounting. Climatic withstand per IACS, and fire resistance tested to 960 °C glow-wire (IEC 60695-2-11).
