Industrial FAP36040 Circuit Breaker

The Square D FA36040 (also cataloged as FAP36040) is a 40‑amp, three‑pole molded‑case circuit breaker in Schneider Electric’s FA I‑Line family for 600‑volt systems. It provides thermal‑magnetic trip protection with a 14 kA short‑circuit interrupt rating at 600 VAC (and up to 250 VDC within the FA family), making it suitable for three‑phase motor and general power‑distribution circuits up to 40 A per pole. This unit is designed for plug‑on mounting in compatible enclosures and is available in variants including top‑feed configurations such as FAP36040TF for installations requiring a top‑feed connection. The FA36040/FAP36040 family supports a broad range of enclosures (NEMA 1/3R/4/4X/5/7/9/12) and is built for a 40°C ambient environment, aligning with typical industrial applications. As part of Schneider Electric’s I‑Line molded‑case breakers, it supports common accessories and provides reliable overload and short‑circuit protection for three‑phase loads in control panels, switchgear, and distribution assemblies.
