Industrial FYB14020A Circuit Breaker

FYB14020A is a 1-pole, 20-amp molded-case circuit breaker from Square D (Schneider Electric), part of the FY family. It is rated for 277 VAC and uses a thermal-magnetic trip mechanism to protect single‑phase distribution circuits from overloads and short circuits. The device is designed for I-Line plug-in mounting in compatible Square D panels, offering a compact, plug‑in solution within commercial and light industrial installations. It carries an 18 kA interrupting rating at 277 VAC, providing robust fault‑current protection for 277‑volt circuits such as lighting or general power distribution in appropriate panel configurations. In this 1P, 20A form factor, the FYB14020A serves as a reliable, single‑pole protective device within I-Line compatible MCCB architectures, balancing compact size with solid overcurrent protection for 277‑volt systems.
