Schneider Electric FAB26015AC I-Line Circuit Breaker

Schneider Electric's FA26015AC (Square D) is a 2-pole, 15-amp, 600-volt I-Line molded-case circuit breaker designed for FA/I-Line panelboards and switchboards. This I-Line style device provides thermal-magnetic overcurrent protection for branch circuits, with interrupting ratings of 18 kA at 480 VAC and 14 kA at 600 VAC under typical conditions, enabling reliable fault interruption across common distribution voltages. The FA26015AC supports 60 Hz systems and is intended for commercial and light industrial applications where I-Line breakers are specified, protecting circuits such as lighting, receptacles, and small motors within the 15 A rating. It is designed to integrate with Square D’s FA/I-Line family for consistent trip characteristics and straightforward replacement in existing installations that specify I-Line protection. Mounting is compatible with I-Line panelboards and switchboards, and the unit is built to meet the needs of panels that require a compact, dependable 2-pole 600 V protection device. For installation, follow the manufacturer’s data for conductor sizing and torque, and ensure compatibility with the specific FA/I-Line panelboard or switchboard in use to maintain proper coordination and safe operation.
