Schneider Electric EHB14030U Molded Case Circuit Breaker

Schneider Electric's Square D EHB14030U molded‑case circuit breaker is a 30‑amp, 277‑volt single‑pole protective device designed for bolt‑on mounting in NEHB panelboards. It accepts 14–8 AWG aluminum or copper conductors and uses a thermal‑magnetic trip mechanism to deliver reliable overcurrent protection for branch circuits. The unit provides a short‑circuit interrupting rating of 14 kA at 277 VAC (and 65 kA at 120 VAC) and is specified for operation in a 40°C ambient environment, making it suitable for typical commercial installations. As part of the EHB series, the 1‑pole design protects individual circuits such as lighting and general power feeds within commercial distribution panels, where a compact, boltable breaker footprint is advantageous. This molded‑case breaker is designed for bolt‑on mounting and compatibility with Square D panel enclosures that support EHB devices.
