FA24020BC - 20 Amp Circuit Breaker

FA24020BC - 20 Amp Circuit Breaker

The FA24020BC from Schneider Electric (Square D I-Line® series) is engineered for dependable circuit protection in demanding electrical environments. Rated at 20 amps and 480 V AC for a 2-pole configuration, this I-Line mounting breaker delivers protection against both overloads and short-circuit faults. With a thermal-magnetic trip unit built in, the FA24020BC gives you the kind of response accuracy you need when system integrity is non-negotiable.

Key Features and Benefits

• Durable Construction: Designed to perform reliably over extended service life in commercial and industrial systems.
• Thermal-Magnetic Trip Technology: Combines time-delay thermal protection for overloads with instantaneous magnetic trip for short circuits — offering a more complete level of protection.
• High Interrupting Capability (Code A): Delivers confidence in fault conditions; the breaker is rated for up to 18 kA at 480 V AC and 25 kA at 240 V AC.
• Compact I-Line Plug-In Mounting: Saves panel space and simplifies installation, especially helpful in tight or retrofitted enclosures.
• Environmentally-Aware Choice: As part of Schneider Electric’s Green Premium® range, the FA24020BC is compliant with RoHS and REACh standards for sustainable projects.
