FH16020C - 20 Amp Circuit Breaker

FH16020C - 20 Amp Circuit Breaker

This FH16020C single-pole 20 Amp circuit breaker from Schneider Electric is designed to deliver dependable protection for your electrical system at 277 V applications. Featuring a thermal-magnetic trip unit, it responds to both sustained overloads and sudden fault currents by blending thermal (overload) and magnetic (short-circuit) protection. Engineered for I-Line mounting, the FH16020C is easy to install and integrates cleanly into existing electrical panels. With high interrupting capacity — filling a breaking-capacity code H rating — this breaker gives you peace of mind under demanding conditions. Whether your site is a manufacturing floor, a large commercial building, or a data centre electrical room, the FH16020C gives you a solid line of defence for your circuits.

Key Features and Benefits

• Thermal-magnetic trip technology: combines overload (thermal) and short-circuit (magnetic) protection in one unit so you’re covered for both typical and fault conditions.
• High breaking-capacity code H: ensures safe interruption of high fault currents, reducing risk to your wiring infrastructure.
• I-Line mount style: plug-in installation means faster set-up, fewer tools and less downtime on installation or replacement.
• Durable, well-specified design: magnetic hold current of 275 A, magnetic trip current of 600 A — these higher-scale ratings mean you get a margin of safety beyond everyday loads.
• Built with sustainability in mind: designed in compliance with key environmental standards, making it a responsible choice for modern installations.

Where It Works Best

• The FH16020C is ideal in commercial or industrial settings where reliable circuit protection is non-negotiable. Think manufacturing facilities, large office buildings, data-processing centres, or any installation with demanding electrical loads. If you’re upgrading switch-gear or retrofitting panelboards that use I-Line mounting, this breaker is a smart fit thanks to its plug-in style and high fault interruption capability. It’s especially useful when you want a component that’s straightforward to install, easy to maintain, and engineered to handle loads beyond everyday operations.
