Schneider Electric FA36020 I-Line Circuit Breaker

Square D by Schneider Electric FA36020 is a gray, 3‑pole molded‑case circuit breaker in the FA I‑Line family, designed for use in FA I‑Line panelboards and other compatible I‑Line systems. It is rated for 20 A at up to 600 V and uses a thermal‑magnetic trip mechanism to protect three‑phase circuits against overload and short circuits. The line side features I‑Line connections, and the load side accepts lugs for 14–4 AWG aluminum or copper conductors, enabling straightforward installation in standard MCCB applications. With an interrupting rating of 14 kA at 600 V, this FA36020 delivers robust short‑circuit protection for distribution feeders in commercial and light industrial environments.
