Square D FA32020 I-Line 3-Phase Circuit Breaker

The Square D FA32020 I-Line 3-Phase Circuit Breaker is a 3-pole, 20-amp molded‑case protective device designed for 240 VAC three‑phase power distribution. It is an FA‑series I‑Line breaker with a plug‑in line‑side connection and ABC phase layout, plus load‑side lugs for wiring, and it employs a thermal‑magnetic trip mechanism with distinct long‑time and instantaneous trip functions to guard against overloads and short circuits. Its electrical ratings include 240 VAC (with a 250 VDC maximum rating) and an interrupt capability typically listed as 10 kA at 240 VAC and 5 kA at 250 VDC, making it suitable for use in Square D I‑Line panelboards and compatible enclosures. This model is intended for use in commercial and light industrial panel assemblies to protect three‑phase equipment such as motors, pumps, and control circuits.
