Square D EHB24050 Two-Pole 50 Amp Circuit Breaker

Square D EHB24050 is a two-pole, 50-amp molded-case circuit breaker built for 480Y/277-volt systems and intended for bolt-on installation in Square D EHB/NEHB panelboards. This protective device accepts 14-2 AWG aluminum or copper conductors and uses a thermal-magnetic trip mechanism to reliably interrupt fault currents and protect feeders and branch circuits. Rated for 14 kA interrupting capacity at 480Y/277 VAC (and 65 kA at 120/240 VAC in appropriate systems), it provides medium‑voltage protection within commercial electrical distributions. As part of the Square D EHB family, the breaker offers rugged, compact construction and is designed for use where space, ease of installation, and compatibility with NEHB panelboards are priorities. The two-pole design supports straightforward protection for multi‑wire, multi‑phase arrangements common in modern commercial panels.
