Schneider Electric EH34015 Molded Case Circuit Breaker

Schneider Electric Square D EH34015 is a three‑pole molded‑case circuit breaker (Type EH) rated at 15 amperes for protecting three‑phase circuits on 480Y/277 VAC systems. This compact MCCB provides thermal‑magnetic overcurrent protection and is designed for use in distribution panels and NF panelboards where reliable feeder and branch‑circuit protection is required in commercial or light‑industrial installations. The EH34015 family covers variants with differing interrupting capacities, so the exact rating must be verified for your specific part number; related models in the same family show ratings ranging from tens of kiloamperes to over 100 kA at 480 V depending on configuration. Typical applications include protecting motors, control circuits, and feeders in three‑phase distribution networks, where a 15 A interrupt level matches loads such as small motors or lighting feeders. The device operates at 277/480 VAC, aligning with common commercial power systems, and its molded‑case design simplifies replacement in existing Square D NF panelboards while maintaining consistent electrical protection and trip characteristics. For precise mounting compatibility and terminal arrangement, confirm the exact variant and refer to the manufacturer’s datasheet for the EH34015 line to ensure correct fit with your panel, enclosure, and wiring scheme.
