Schneider Electric Square D EH14020 Circuit Breaker

Schneider Electric Square D EH14020 is a single-pole, 20-amp circuit breaker designed for 277 V AC circuits. As part of the Square D EH family of molded‑case breakers, the EH14020 is designed for plug‑in installation in compatible panelboards and enclosures and uses a thermal‑magnetic trip that coordinates with other EH devices to provide selective protection and minimize nuisance trips in busy panels. It accepts 14–8 AWG copper or aluminum conductors in standard terminals and offers a 14 kA interrupting rating at 277 VAC, enabling rapid fault interruption while meeting typical electrical-code requirements for small branch circuits in commercial settings such as lighting or general power distribution. The EH14020 designation identifies the device within Schneider Electric's Square D lineup, providing reliable overcurrent protection for a dedicated 20 A line and offering compatibility with other EH-series devices across industrial and commercial panel systems used in offices, retail spaces, and light‑industrial environments.
