Schneider Electric FA26020AC I-Line Circuit Breaker

Schneider Electric FA26020AC is a Square D FA family I‑Line molded‑case circuit breaker, a 2‑pole, 20‑amp device designed for industrial power distribution. It is rated for up to 600 VAC (and 250 VDC) and uses a thermal‑magnetic trip mechanism to protect against overloads and short circuits, making it suitable for feeders and branch circuits in FA I‑Line panelboards and switchboards. The unit features an I‑Line line connection with load‑side lugs for 14–4 AWG aluminum or copper conductors, and is specified for FA I‑Line plug‑in installations. Its interrupting rating is listed as up to 14 kA at 600 VAC, with higher ratings at lower voltages (25 kA at 240 VAC and 18 kA at 480 VAC, depending on system voltage). This 20 A, 2‑pole breaker is commonly used in industrial control panels and motor control centers to provide reliable protection for single‑phase or 2‑phase circuits within appropriate FA‑Series applications.
