Industrial EHB34025 Circuit Breaker

Square D (Schneider Electric) EHB34025 is a 25 A, three-pole bolt-on molded-case circuit breaker designed for legacy NEHB panelboards. It provides thermal-magnetic overcurrent protection for 480Y/277 VAC three-phase systems and accepts 14–8 AWG copper or aluminum conductors. The device carries interrupting ratings of 14 kA at 480/277 VAC and 65 kA at 240 VAC, enabling fast fault interruption across a range of industrial fault currents. This breaker is specified for NEHB panelboards and is typically used to protect feeders and branch circuits in commercial or light-industrial installations where Square D legacy hardware remains in service. The bolt-on EHB34025 fits into compatible NEHB panelboard assemblies and works alongside other Square D/Schneider Electric protection devices to maintain coordinated protection across the distribution system.
