FY14020B - 20 Amp Circuit Breaker

FY14020B - 20 Amp Circuit Breaker

When you want reliable protection for your electrical system without over-complicating things, the FY14020B delivers. This thermal-magnetic single-pole breaker from Schneider Electric fits standard I-Line mounting and is built to safeguard your circuits from overloads and short-circuit events. With a 20 Amp rated current and a 277 VAC voltage rating, it’s an excellent choice for lighting and other branch circuits in both commercial and light industrial settings. Whether you’re upgrading an existing panelboard or stocking up for new installs, this 20 A breaker offers peace of mind with performance you can count on.

Key Features and Benefits

• Dependable thermal-magnetic trip unit: The breaker uses a combined thermal (for overload) and magnetic (for short-circuit) mechanism so you get consistent protection when it matters.
• I-Line plug-in design and lug load connections: Makes installation quicker and more secure, reducing the chance of wiring issues or loose connections on site.
• High magnetic trip values: Including approx. 275 A hold current and 600 A instantaneous trip current — give strong protection against significant fault currents and help safeguard circuits and equipment.
• Compact size: At just 1.5 in wide by 6.4 in high by 4.13 in deep (≈ 38.1 mm × 162.6 mm × 104.9 mm), it fits well in modern panelboards where space is at a premium.
• Recognised brand and build quality: As a product from Schneider Electric’s legacy Square D family, the FY14020B carries the confidence of a manufacturer with a strong reputation in electrical protection devices.
