It uses the EH frame design, which supports stable performance and consistent trip characteristics in a wide range of electrical environments. The breaker includes long-time and instantaneous trip functions, making it suitable for circuits where both overload resilience and fast fault clearing are required. Its 14 kA interrupt rating at 240–277V AC allows it to be used effectively in commercial and light industrial systems.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong data-start=\"1085\" data-end=\"1102\"\u003eKey Features:\u003cbr\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e40A Rating: Provides branch-circuit protection for moderate electrical loads in 277\/480V systems.\u003c\/li\u003e\n\u003cli\u003eTwo-Pole Design: Supports single-phase applications requiring simultaneous disconnection of both conductors.\u003c\/li\u003e\n\u003cli\u003eThermal-Magnetic Trip: Ensures precise response to overloads and short-circuit conditions.\u003c\/li\u003e\n\u003cli\u003eBolt-On Connection: Offers secure mounting and stable electrical contact within compatible panelboards.\u003c\/li\u003e\n\u003cli\u003eLI Trip Functions: Features long-time and instantaneous protection for versatile fault-handling capability.\u003c\/li\u003e\n\u003cli\u003eEH Frame Construction: Delivers consistent mechanical durability and reliable trip performance.\u003c\/li\u003e\n\u003cli\u003e14 kA Interrupt Rating: Allows safe clearing of higher-energy faults in commercial applications.\u003c\/li\u003e\n\u003cli\u003e277\/480V Compatibility: Suitable for a wide range of building and equipment power distribution systems.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe EHB24040 delivers the reliability and precision required for dependable molded case circuit protection in commercial and industrial installations.\u003c\/p\u003e","brand":"Schneider Electric","offers":[{"title":"Default Title","offer_id":50852013375786,"sku":"EHB24040","price":1212.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/0392\/4266\/files\/2025-11-19_16.46.05.png?v=1763563577","url":"https:\/\/iqelectro.com\/products\/square-d-ehb24040-40a-2-pole-circuit-breaker-available-now","provider":"IQElectro","version":"1.0","type":"link"}
