Schneider Electric EHB34020 BoltOn Circuit Breaker

The Schneider Electric EHB34020 is a 20A, 3-pole, bolt-on molded‑case circuit breaker designed for 480Y/277 VAC three‑phase distribution. Part of the Square D EHB family, this thermal‑magnetic device protects three‑phase circuits by interrupting fault currents and overloads to help prevent equipment damage. It mounts directly to compatible panels with bolt‑on lugs and uses an E‑Frame construction for reliable seating in legacy Square D bolt‑on configurations. The EHB34020 carries a short‑circuit interrupting rating of 65 kA at 240 VAC and 14 kA at 480 VAC, making it suitable for mid‑size industrial and commercial panelboards that require robust protection in 480Y/277 VAC systems.
