Product details

The G12F3A32 is a 3-pole GoPact MCCB 125 with a TM-D thermal-magnetic trip unit rated 32 A at 40 °C. The thermal-magnetic LI protection (L for overload, I for short-circuit) is the standard two-step curve for cable and busbar protection in a distribution board. Rated operational voltage is 415 V AC 50/60 Hz per EN/IEC 60947-2, with a rated insulation voltage of 440 V AC. If your panel ambient runs higher, the breaker must be derated per the manufacturer's thermal curve — standard practice for any thermal-magnetic MCCB in a warm enclosure.

Deployment context

Fixed-mount MCCB with front-front connections (line and load both terminate on the front face) and screw terminals. Mounts flat on a backplate in either horizontal or vertical orientation. The 25 mm connection pitch matches standard busbar and cable-lug spacing for panel builds. IP20 finger-safe terminals are adequate for enclosed distribution boards but not for washdown environments.
