FY14030B - 30 Amp Circuit Breaker

FY14030B - 30 Amp Circuit Breaker

Meet the FY14030B 30 Amp single-pole molded-case breaker from Schneider Electric (via its Square D brand line) — designed to deliver dependable circuit protection in commercial and industrial electrical systems. This thermal-magnetic breaker combines precise overload and short-circuit response with a compact I-Line®-friendly form factor, making it a smart choice when safety, space, and performance matter. With its 30 A rating and 18 kA interrupting capacity, the FY14030B is built to keep your distribution network secure and operational.

Key Features and Benefits

• Thermal-Magnetic Trip Unit: Incorporates both heat-based (thermal) and magnetic trip elements, giving you reliable protection against overloads and high-fault events in one device.
• High Interrupting Capacity: Rated at up to 18 kA (with 14 kA noted on some spec sheets) at 240 / 277 V, the breaker is ready to handle significant fault currents, helping protect downstream equipment and reduce system damage.
• I-Line® Mounting Compatibility: Designed for easy integration into I-Line bus systems, enabling quick installation and efficient retrofit or upgrade of existing panels.
• Compact Footprint: With a width of just 1.5 inches and overall small size (approx. 6.4″ H × 1.5″ W × 4.13″ D), it preserves valuable panel space without sacrificing protection.
• Green Premium Label (Sustainability-Focused): Built in line with Schneider Electric’s sustainability standards to minimize environmental impact, making it a forward-looking choice for eco-conscious facilities.
