Product details

The Schneider Electric G12T3A32 is a GoPact MCCB 125 thermal-magnetic circuit breaker, 3-pole, rated 32 A at 40 °C with a breaking capacity of 10 kA at 380/415 V AC (performance level T).

The 32 A thermal-magnetic trip unit (TM-D) provides LI protection — thermal for overload (L) and magnetic for short-circuit (I). Rated insulation voltage is 440 V AC, and operational voltage is 415 V AC 50/60 Hz — both per IEC 60947-2. The IP20 finger-safe enclosure keeps live parts protected but does not tolerate washdown or dust. Mechanical durability is 30 000 cycles; electrical durability is 8 000 cycles at In at 415 V. Power dissipation per pole is 18.7 W, so panel thermal calculations should account for about 56 W total across three poles at full load.

Fixed mounting on a backplate, with front connections (upside and downside) via screw terminals. Connection pitch is 25 mm. Dimensions: 130 mm high, 75 mm wide, 60 mm deep. Colour is grey RAL 7035. The toggle control type provides manual on/off and tripped indication.
