Schneider Electric ehb14020 1 Pole 20 Amp Circuit Breaker

Square D by Schneider Electric EHB14020 is a 1-pole, 20-amp miniature circuit breaker in the EHB family, designed for use in Square D NF panelboards. Rated for 277 VAC operation, it employs a thermal-magnetic trip mechanism to provide inverse-time protection for branch circuits. The device is 1P, 20A, with an interrupting rating of 65 kA at 120 VAC and 14 kA at 277 VAC, enabling it to safely interrupt fault currents. Common applications include commercial lighting circuits, 277 VAC power feeds, and other branch circuits in 277-volt distribution systems using Square D panel infrastructure. Designed for use in commercial settings, it coordinates with other E-frame breakers in Square D NF panelboards and is suitable for 277V lighting and power circuits found in offices, retail spaces, and hospitality environments. As part of the E-Frame line, the EHB14020 aligns with the form factor and mounting scheme of other EHB/MCBs, delivering reliable overcurrent protection for 20A circuits within Schneider Electric's panel ecosystems.
