Schneider Electric FA-26040-AC Circuit Breaker

Schneider Electric’s Square D FA26040AC molded‑case circuit breaker is a 40 A, 600 V AC, 2‑pole device from the FA (F‑Frame) family that employs a thermal‑magnetic trip mechanism to protect circuits against overloads and short circuits in distribution equipment. Built for I‑Line mounting, it fits into panelboards and switchboards that support FA‑series MCCBs, making it suitable for commercial and light‑industrial power‑distribution applications where compact, high‑reliability protection is required and field replacement or maintenance can be straightforward. Core specifications include a 600 VAC rating, 40 A current rating, 2‑pole configuration, and molded‑case construction; the FA26040AC variant is widely listed by Schneider Electric and distributor networks as a 40 A, 600 V MCCB designed for I‑Line panel integration.
