Schneider Electric FA26020AC I-Line Circuit Breaker

Schneider Electric's Square D FA26020AC is a 20-amp, 600-volt two‑pole molded‑case circuit breaker from the FA I‑Line family, designed for single‑phase feeder protection in FA‑type panelboards. It provides thermal‑magnetic protection with a standard AC trip and is intended for use with I‑Line plug‑in mounting. The unit offers interrupting ratings of 25 kA at 240 VAC, 18 kA at 480 VAC, and 14 kA at 600 VAC, giving it flexibility across mid‑voltage installations. Rated at 80% for continuous operation, the FA26020AC is built for industrial control and machinery feeders, with line‑side I‑Line connections and load‑side lugs, and it supports aluminum or copper conductors on the wiring terminals. This 2‑pole, 1‑phase device is part of Schneider Electric’s legacy FA I‑Line lineup, designed for reliable overload and short‑circuit protection in compact MCCB form factors and compatible with FA‑series accessories and FA panelboard configurations for consistent performance with other FA 20‑A devices.
