Schneider Electric FA-34070 I-Line Circuit Breaker

Schneider Electric FA34070 I-Line Molded‑Case Circuit Breaker is a 70‑amp, three‑pole device designed for 480 VAC three‑phase power distribution in FA I‑Line panelboards. As part of the FA (F‑Frame) I‑Line family, this 70 A unit provides thermal‑magnetic protection for industrial circuits and is intended for plug‑in installation within Schneider Electric’s FA I‑Line panel systems. The FA34070 is rated for 480 V operation and configured in a 3‑pole arrangement to protect three‑phase loads, such as motors and other heavy machinery, in commercial and industrial facilities. Schneider Electric discontinued the FA34070 from commercialization on November 11, 2020, with the manufacturer signaling a path forward through PowerPact B replacements for continued support and modernization. The recommended upgrade path from Schneider Electric’s documentation for this reference is a PowerPact B family unit rated at 70 A and 3 poles, compatible with 600Y/347 VAC service and offering an interrupting capacity of 14 kA, with the replacement part identified as BDA36070, preserving I‑Line compatibility in new installations or retrofits.
