Product details

The G12T3F100 is a 3-pole GoPact MCCB 125 from Schneider Electric, rated 100 A at 40 °C with a TM-D thermal-magnetic trip unit. It carries a 10 kA breaking capacity at 415 V AC (50/60 Hz) per IEC 60947-2, making it a straight choice for distribution panels where you need overload and short-circuit protection in one package.

The LI protection (thermal for overload, magnetic for short circuit) covers the two most common fault types in distribution.

The 25 mm connection pitch matches common busbar and lug spacing. IP20 finger-safe terminals are fine inside a closed panel; no washdown rating here, so keep it dry.
