Square D By Schneider Electric FA36015 I-Line Circuit Breaker

The Square D by Schneider Electric FA36015 I-Line Molded Case Circuit Breaker is a 3‑pole, 15‑amp protection device designed for I‑Line panelboards in three‑phase distributions. Part of the FA family, it is rated for up to 600 VAC and 250 VDC, with a thermal‑magnetic trip mechanism and a line‑side I‑Line connection plus load‑side lugs. It accepts 14–4 AWG copper or aluminum conductors and is 80% rated for continuous duty. Its interrupting ratings vary by voltage: up to 25 kA at 240 VAC, 18 kA at 480 VAC, and 14 kA at 600 VAC, with 10 kA at 250 VDC. The unit follows the FA/F‑frame form factor, with approximate dimensions of 4.5 in wide, 4.13 in high, and 6.4 in deep. This model is suited for protecting feeders and distribution circuits in commercial and light‑industrial power systems that employ 600 VAC three‑phase service and I‑Line plug‑on mounting for reliable overload and short‑circuit protection.
