FC34020 - 20 Amp Circuit Breaker

FC34020 - 20 Amp Circuit Breaker

Discover a dependable industrial circuit-breaker solution with the FC34020 from Schneider Electric’s Square D line—designed to provide high-capacity protection in heavy-duty electrical systems. Built as a 3-pole, 20-amp thermal-magnetic molded-case breaker, it combines reliable performance and enhanced safety features to ensure your panelboards, enclosures or switchboards operate confidently under stress. Whether you’re managing a manufacturing floor, a busway plug-in unit or an I-Line panelboard setup, this breaker gives you strong protection when faults or overloads occur.

Key Features and Benefits

• High Interrupting Capacity: Rated at 65 kA at 480 VAC and 100 kA at 240 VAC, this breaker is ready to clear large fault currents that lesser devices might struggle with—giving you peace of mind in demanding installations.
• Thermal-Magnetic Trip Mechanism: The dual-trip design responds to sustained overloads via the thermal element, and instant high-fault conditions via the magnetic portion—so you get broad protection against both everyday over-currents and sudden shorts.
• Molded-Case Design for Durability: The breaker’s molded housing helps it endure industrial environments—maintaining consistent functionality and reducing the need for frequent replacements or service interruptions.
• Panelboard Compatibility: HACR-type certified and suitable for I-Line panelboards, this breaker integrates into a wide range of systems – making it a flexible choice for many electrical infrastructure projects.

Where It Works Best

• This FC34020 breaker is ideally suited for industrial installations where reliable circuit protection is non-negotiable. Use it in panelboards, switchboards, or busway plug-in units that handle heavy machinery, motors, or distributed loads with potential for high fault current. If you’re running a system with frequent over-current risk or require a breaker that won’t be the weak link under fault conditions, this is a strong choice. Its compatibility with I-Line panelboards also makes it a flexible option for many facility upgrades or new builds.
