Schneider Electric BJA36100 I-Line Circuit Breaker

Schneider Electric BJA36100 is a PowerPact B-frame molded‑case circuit breaker engineered for I‑Line panel protection. The 3‑pole device carries a 100 A rating and is configured for 600Y/347 VAC systems, offering an interrupting capacity of 25 kA at the rated voltage. It uses I‑Line plug‑on mounting for secure, tool‑less installation in Schneider Electric’s I‑Line panelboards, and it comes with a non‑interchangeable trip assembly. As part of the PowerPact B family, the BJA36100 protects three‑phase feeders in commercial and light‑industrial distribution gear, providing thermal‑magnetic overcurrent protection that reacts to both overload and short‑circuit conditions. The model is widely cataloged under Square D by Schneider Electric, with official product pages and regional listings confirming its 100 A, 3P, 600Y/347 VAC, I‑Line specifications and its place in the PowerPacT B‑Frame lineup. Its 3‑pole configuration is suitable for balanced 3‑phase systems common in many commercial applications.
