The G12LTSHD4P is a long terminal shield from the Schneider Electric GoPact MCCB range, sized for 4-pole MCCBs in the 125 A frame. It's an insulation accessory — not a functional breaker — so the IP40 rating (per IEC 60529) tells you it keeps fingers and tools off live busbars inside the panel, but it's not sealed against washdown. Fits upstream or downstream of the breaker, which matters when you're laying out the gland plate and need to keep phase spacing consistent on the line side.
Panel fit
Mounts directly onto the GoPact MCCB 125 terminal studs. No extra hardware needed — it's a slide-on fit that captures the outgoing cable lugs. The 4-pole version covers all phases plus neutral in a single piece, which keeps the fill factor tight on the DIN rail. If you're wiring a motor control center bucket, this shield buys you the IP40 finger protection without eating up extra enclosure depth.
