The Schneider Electric G12E3A32 is a GoPact MCCB 125 moulded-case circuit breaker, 3-pole, with a TM-D thermal-magnetic trip unit rated 32 A at 40 °C. It provides LI protection — thermal for overload (L) and magnetic for short-circuit (I) — and is rated for distribution duty in a fixed-mount, backplate installation.
The 15 kA Icu at 415 V AC (50/60 Hz) is the ultimate short-circuit breaking capacity; for selectivity studies use the Ics (service breaking capacity) which is typically 100% of Icu for this class. The 8000 electrical cycles at rated current cover normal switching duty; 30000 mechanical cycles give the handle a long service life in a distribution board that sees infrequent manual operation.
Fixed-mount on a backplate, accepts front-connect screw terminals top and bottom. The 25 mm connection pitch matches standard busbar and cable-lug spacing for 3-pole breakers. Mount horizontally or vertically flat on the back; no derating needed for orientation.
