Schneider Electric BGA36125 I-Line Circuit Breaker

Schneider Electric's PowerPact B I‑Line molded‑case circuit breaker, model BGA36125, is a 3‑pole, 125 A protective device designed for 600Y/347 VAC service within PowerPact B‑Frame panels. It provides thermal‑magnetic overcurrent protection with an 18 kA interrupt rating at 600Y/347 VAC and is rated for 50/60 Hz operation. This BGA unit integrates into Schneider Electric’s I‑Line system and accepts I‑Line/Mechanical Lug termination with aluminum or copper conductors ranging from 14 AWG to 2/0 AWG, and it measures about 5.39 in high, 3.19 in wide, and 3.50 in deep; the enclosure is rated IP40/IK07. The device is intended for branch‑circuit protection in commercial and light industrial distributions, where a 125 A rating and three poles support coordinated protection for motors, transformers, and loads, with an 80% continuous‑load rating for typical installations. The BGA36125 is part of the PowerPact B family and is commonly paired with other I‑Line components to create compact, bus‑connected protection in Schneider Electric switchgear and panel boards.
