Schneider Electric FY14020B I-Line Circuit Breaker

Schneider Electric's Square D FY14020B is a 20-amp, 277-volt I-Line molded‑case circuit breaker designed for plug‑in installation in Square D I‑Line panelboards. This 1‑pole, Type FY device provides branch‑circuit protection for 277 VAC circuits and is built as part of the I‑Line family to fit the panelboard distribution architecture that supports quick replacement and dependable connections. The FY14020B uses thermal‑magnetic trip protection, a characteristic of FY‑series breakers, delivering fast, selective tripping to isolate faults without unnecessary outages. Ideal for commercial and light‑industrial applications such as lighting runs, outlets, and control circuits powered from 277 VAC systems, it is intended to pair with I‑Line panelboards and compatible Square D breakers and accessories to provide compact, space‑efficient overcurrent protection.
