Schneider Electric SE EH34030 Circuit Breaker

Schneider Electric's Square D EH34030 is a Type EH molded‑case circuit breaker designed for 480Y/277 VAC three‑phase systems. This 3‑pole, 30‑amp device is a plug‑on breaker intended for NEH panelboards, offering compact, modular protection for distribution feeders in commercial or light‑industrial power networks. It delivers an interrupting capacity of 14 kA at 480/277 VAC (65 kA at 240 VAC), providing reliable fault interruption for 3‑phase circuits up to 30 A. The EH34030 integrates with other EH‑series breakers for straightforward common‑trip coordination and retrofit into compatible Square D panelboards. Use this breaker to safeguard downstream equipment such as motors, air handling units, compressors, and other 480Y/277 VAC loads that require 30 A protection with a three‑pole configuration. When selecting, confirm that the panelboard accepts Type EH, 3‑pole, 30 A plug‑on breakers and that the installation complies with applicable electrical codes and the panel’s listings.
