Square D FI26030AC Industrial Circuit Breaker

Square D by Schneider Electric FI26030AC is a two-pole industrial circuit breaker rated for 30 amps at up to 600 volts, catalog number FI26030AC. Marketed by retailers as a current-limiting circuit breaker, this device is designed to interrupt fault currents in power-distribution circuits, protecting both conductors and connected equipment in commercial and industrial installations. The 30 A / 600 V rating defines its protective envelope for feeders and branch circuits within panels and enclosures that operate at those voltages. With its two-pole configuration, it provides simultaneous disconnection of both live conductors on fault, helping to safely isolate faults and reduce damage to downstream equipment. This model is part of Square D’s FI family, offering a compact, dependable solution when space in industrial control panels is at a premium. Ideal use cases include protection of motor control circuits, control panels, and other intermediate-load circuits in manufacturing facilities, processing plants, and facilities with 600 V class electrical systems.
