Square D EHB34070 Molded Case Circuit Breaker

Square D EHB34070 Molded Case Circuit Breaker is a 3-pole, 70-amp unit rated for 480Y/277V three-phase service. Built on Square D's EHB molded-case frame, this thermal-magnetic circuit breaker provides overcurrent protection for feeders and branch circuits in industrial distribution panels. Designed for commercial and light-industrial installations, the EHB34070 supports high-voltage applications where reliable interruption at 480Y/277 VAC is required and offers the rugged, self-contained housing characteristic of molded-case devices. Key details include a 3-pole configuration, 70 A rating, voltage rating of 480Y/277 VAC, and a molded-case construction that protects internal components while simplifying mounting in compatible panelboards. The unit is part of Square D's legacy MCCB lineup and is used to protect electrical circuits from overloads and short circuits, ensuring safer power distribution in demanding environments.
