Built to deliver effective performance in demanding settings, this three-pole, I-Line mount breaker handles 20 amps at up to 480 V AC with confidence. Its thermal-magnetic trip unit provides reliable protection against overloads and short-circuit faults, giving you peace of mind for your electrical system. Whether you're managing a residential upgrade, light commercial retrofit, or industrial panel configuration, the FA34020 brings a blend of precision, flexibility and safety to the table.

Key Features and Benefits

• Thermal-Magnetic Trip Unit: The combination of a thermal (long-term overload) and magnetic (short-circuit) mechanism ensures that both gradual and sudden fault conditions are handled properly—less risk, fewer surprises.
• High Interrupting Capacity: Rated to interrupt up to 18 kA at 480 V AC (and higher values at lower voltages), this breaker is designed to withstand serious fault events without failing.
• I-Line Plug-On Mounting: Designed to plug into I-Line panels for quick installation and minimal wiring hassle—ideal when you’re upgrading or replacing in an existing panel board.
• Three-Pole Design: Perfect for three-phase applications where you need balanced protection across all phases.
• Compact Profile: With dimensions around 6.4″ H × 4.5″ W × 4.13″ D and a weight around 6.23 lb, it fits neatly into many panel arrangements.
