Schneider Electric FA22070AC BU Circuit Breaker

Schneider Electric's Square D FA22070AC is a 70-amp, 240-volt two-pole molded‑case circuit breaker in the FA/I‑Line family, designed to provide thermal‑magnetic protection for feeders and branch circuits in panelboards and switchboards. Rated for 240 VAC operation, it carries a 70 A rating and uses a two‑pole, two‑phase configuration to interrupt fault currents and protect downstream loads. The FA22070AC is listed for an interrupting capacity around 10 kA at 240 V, and accepts aluminum or copper conductors up to 1/0 AWG on the line and load sides, matching common industrial wiring practices. This model is widely used in commercial and light industrial electrical distributions where compact MCCB protection is required, and it pairs with Square D I‑Line enclosures and associated bus assemblies for straightforward integration into existing panels.
