Fast Shipping Square D EHB34045 – 45A 3 Pole Molded Case Circuit Breaker

Built specifically for commercial power distribution, this 45-amp device handles demanding three-phase loads. It mounts into legacy Square D NEHB panelboards, serving as a critical maintenance component for facilities that have not yet transitioned to modern NF enclosures. The unit provides robust fault clearing with a 65kA interrupting capacity at 240VAC. Operators benefit from the built-in Visi-Trip visual indicator, which simplifies troubleshooting by clearly identifying tripped circuits.
