FCL34020 - 20 Amp Circuit Breaker

FCL34020 - 20 Amp Circuit Breaker

When you’re installing or upgrading electrical protection in industrial or commercial systems, the FCL34020 delivers dependable performance you can count on. Built on the FCL frame and engineered with both thermal and magnetic trip mechanisms, this 20 A breaker is designed to respond fast to faults while giving you long-term service in demanding environments. Whether you’re running a motor control center, switchboard, panelboard or plug-in busway unit, this breaker gives you the safety and functionality your system requires.

Key Features and Benefits

• High fault-interrupting capacity: With ratings of up to 65 kA at 480 VAC and 100 kA at 240 VAC, this breaker is capable of handling major fault currents — giving you added protection and peace of mind.
• Thermal and magnetic trip protection: Combining both mechanisms means sensitive response to overloads (thermal) and fast reaction to short-circuits (magnetic), helping keep your system safe and healthy.
• Three-pole configuration: Ideal for balanced load systems and three-phase use, this design supports comprehensive protection across all three phases.
• Durable molded-case construction: Designed to stand up to the harsh realities of industrial use — from electrical stress to environmental conditions — so it performs reliably over time.
• Wide applicability: Suitable for use across multiple applications — industrial enclosures, panelboards, switchboards, combination starters and plug-in busway units — which gives you flexibility and reduces the need for multiple product types.
