Schneider Electric FH26030AC I-Line Circuit Breaker

Schneider Electric's Square D FH26030AC I-Line molded-case circuit breaker is a two-pole, 30-amp, 600-volt AC thermal-magnetic device designed for use in Square D I-Line panelboards and switchboards. As part of the FH family, it uses line-side I-Line connectors and an AC phase connection for a 1‑phase, 2‑pole circuit, with a typical A–C phase configuration. The unit accepts 14-4 AWG aluminum or copper conductors on the line side and is rated for 40°C ambient operation. It provides an interrupting rating of 65 kA at 240V, 25 kA at 480V, and 18 kA at 600V, making it suitable for building-level service and branch circuits with moderate fault currents. This 30 A breaker employs a thermal-magnetic trip mechanism to protect against overloads and short circuits and is designed for plug-in installation in FH‑class I‑Line panels, commonly used to protect lighting and receptacle circuits or small-motor loads within its 30 A rating.
