Schneider Electric's Square D EDB14020 is a 1‑pole, E‑Frame bolt‑on miniature circuit breaker rated for 20 A at 277 V AC, designed for use in Square D NF panelboards. It uses a thermal‑magnetic trip for overcurrent protection and carries a maximum interrupting rating of 25 kA. The device accepts 12–14 AWG conductors and mounts via a bolt‑on method suited to NF panelboard installations, with dimensions roughly 0.98 in wide by 4.05 in deep by 5.66 in tall. It is TAA‑compliant and targeted at protecting branch circuits in commercial or industrial NF panelboard environments, commonly used for lighting and general loads in 277 V systems.
