FA24050AB - 50 Amp Circuit Breaker

FA24050AB - 50 Amp Circuit Breaker

When you need reliable circuit protection in demanding environments, the Schneider Electric FA24050AB stands out. This 2-pole, 50 A breaker is engineered for 480 V AC systems and done in the I-Line® mounting style, delivering dependable overload plus short-circuit coverage with a thermal-magnetic trip unit. Whether you’re working in a light industrial control panel, a commercial site, or a high-end residential application, the FA24050AB offers the kind of dependable performance that keeps systems safe and compliant.

Key Features and Benefits

• Thermal-magnetic trip mechanism: Combines long-time protection for overloads with instantaneous response for short-circuit events, providing dual-mode coverage for greater safety.
• High interrupting capacity (Breaking-capacity code A): Designed to safely interrupt fault currents (e.g., rated up to 18 kA at 480 V AC) so your equipment and wiring are better guarded.
• I-Line mounting format: Allows fast drop-in installation in compatible panels, simplifying replacement and reducing downtime.
• 2-pole, single-phase (A-B) configuration: Ideal for 480 V branch-circuit use, giving you flexibility in commercial or industrial set-ups.
• Comprehensive connectivity: Accepts copper or aluminum cables (as per specification: AWG 14…1/0 Cu, AWG 12…1/0 Al) and provides robust load and line lug options.
