Schneider Electric SE EHB34030 Circuit Breaker

Schneider Electric's Square D EHB34030 is a bolt-on, three-pole circuit breaker rated for 30 A at 480 V, intended for use in EHB-4 frame panelboards and other compatible Square D enclosures. The thermal-magnetic device provides overcurrent protection for 3-phase circuits, with an interrupting capacity of 65 kA at 240 V and 14 kA at 480 V, making it suitable for industrial distribution where high fault currents may be encountered on the 480 V feeders. It is designed for bolt-on mounting, allowing straightforward installation in frames built to accept the EHB series. The EHB family is used to protect branch circuits and feeders in commercial or light industrial electrical panels, including motor control and power distribution applications that operate at 480 V. When selecting the EHB34030, confirm that the target panelboard supports EHB-frame breakers and follow all local electrical codes and manufacturer installation instructions to ensure proper fit and electrical performance. This specific model—three poles, 30 A, 480 VAC, Square D (Schneider Electric)—is part of the EHB lineup, balancing compact 3P protection with robust interrupting ratings for demanding 480 V systems.
