Schneider Electric FA26020AB I-Line Circuit Breaker

Schneider Electric FA26020AB is a two-pole, 20-amp I-Line molded‑case circuit breaker designed for use in Square D I‑Line panelboards and switchboards. It is rated for up to 600 VAC (and 250 VDC) and uses a thermal‑magnetic trip mechanism for overload and short‑circuit protection. The unit features a Line Side I‑Line connection and AB phase configuration with load‑side lugs, and it accepts aluminum or copper conductors up to 14‑4 AWG. As part of the FA I‑Line family, this 20 A, 2P breaker provides an 80% continuous‑load rating with an interrupting capacity of 25 kA at 240 V, 18 kA at 480 V, and 14 kA at 600 V, making it suitable for protecting feeders and branch circuits in industrial control panels and switchboards that require I‑Line compatibility.
