Square D EH34015U Three Phase Circuit Breaker

Square D EH34015U is a three-pole molded-case circuit breaker from Square D by Schneider Electric, rated for 15 amperes in a 480-volt three-phase distribution. As a member of the EH-series family, this device is designed for panelboards and switchgear that accept EH-frame breakers and provides protection for branch circuits against overloads and short circuits in 480V three-phase systems. The 3P, 15A rating makes it suitable for smaller feeders and equipment within a 480V network, enabling safe isolation of circuits during faults. The EH34015U’s molded-case construction supports straightforward installation in compatible enclosures and helps maintain clear, organized distribution layouts in commercial or light industrial electrical distributions. Built to align with Square D’s line, it shares common installation philosophy with other EH-series breakers, which simplifies future expansions or replacements within the same panel ecosystem.
