Schneider Electric FA26020BC I-Line Circuit Breaker

FA26020BC is a Square D by Schneider Electric FA-series I-Line molded‑case circuit breaker, 2‑pole, 20 A, designed for 600 V operation (600 VAC / 250 VDC) and 1‑phase systems. It uses line‑side I‑Line connections and I‑Line plug‑in construction compatible with FA I‑Line panelboards, typically installed as a 2P, 1PH device in commercial or light industrial distributions. This thermal‑magnetic MCCB accepts 14‑4 AWG aluminum or copper conductors on the load side with standard lugs, and it features I‑Line drawout connectors for secure mounting. The FA26020BC has interrupting ratings that vary by voltage: up to 25 kA at 240 V, 18 kA at 480 V, and 14 kA at 600 V, and it is rated for 40°C ambient with an 80% continuous‑load rating. Use cases include protecting branch circuits in panelboards and distribution equipment where FA I‑Line protection is specified, providing reliable overload protection with FA‑series trip characteristics.
