Schneider Electric FA32020 I-Line Circuit Breaker

Schneider Electric Square D FA32020 is a 3‑pole, 20‑amp I‑Line molded‑case circuit breaker built on the FA frame for 240 V three‑phase service. It supports an I‑Line plug‑in connection on the line side and load‑side lugs, accepts conductor sizes #14–4 AWG aluminum or copper, and uses a thermal‑magnetic trip with an 80% continuous‑duty rating. This FA32020 is intended for use in I‑Line panelboards and switchboards in industrial electrical distributions, providing protection for 3‑phase circuits in compact panel installations. Some FA32020 variants are rated for higher voltages (up to 480Y/277 VAC in other configurations), with corresponding adjustments to interrupting ratings; always confirm the exact rating from Schneider Electric's datasheet for your installation. Typical applications include protection of 3‑phase motors, pumps, and automated process lines in medium‑to‑large electrical distributions; this device is designed for panel builders and installers who require quick, plug‑in replacement within FA‑frame I‑Line installations. Compatible with Square D I‑Line system accessories and mounting hardware; the FA32020 is part of Schneider Electric's PowerPact B family of MCCBs.
