Square D EDB34070AABA 3-Pole 70A Bolt-On Circuit Breaker

The Square D EDB34070AABA is a high-performance, bolt-on molded case circuit breaker designed for commercial and industrial electrical distribution systems. Part of the EDB series, this 3-pole breaker provides reliable overcurrent protection with a 70A continuous current rating, suitable for applications up to 480Y/277V AC. It features thermal-magnetic trip technology for precise protection against overloads and short circuits, with interrupting capacities of 25kA at 240V and 18kA at 480Y/277V. Key benefits include compact design for easy installation in NF panelboards, HACR rating for heating, air conditioning, and refrigeration equipment, and robust construction for demanding environments. Advantages over similar products include Square D's reputation for durability and compatibility with Schneider Electric systems, though it may require specific panel compatibility checks. Drawbacks could include higher cost compared to residential-grade breakers and the need for professional installation. Ideal for lighting panels, motor controls, and branch circuit protection in facilities like offices, factories, and data centers. Based on image analysis, the unit appears in good used condition with minor wear on terminals, includes an auxiliary switch (AABA suffix), and shows no visible damage. Serial number visible as 1915 105, suggesting manufacture around 2019.
