Schneider Electric FA26020BC I-Line Circuit Breaker

Schneider Electric's FA26020BC is a 20 A, two-pole, single‑phase I‑Line molded‑case circuit breaker designed for use in Square D FA I‑Line panelboards. It accepts 14‑4 AWG aluminum or copper conductors on the load side and features line‑side I‑Line connections with BC phase jaws for a proper, plug‑in fit. Rated for up to 600 VAC and up to 250 VDC, the FA26020BC uses a thermal‑magnetic trip mechanism and is 80% rated for continuous operation. The device carries interrupting capabilities of 25 kA at 240 V, 18 kA at 480 V, and 14 kA at 600 V, and it is specified for operation at ambient temperatures up to 40°C. This FA I‑Line breaker provides reliable branch‑circuit protection in commercial or industrial electrical distributions and is intended for quick replacement in FA I‑Line panelboards where space and standardization matter.
