This 3 pole breaker features a 20A current rating, 480V AC voltage rating, and is built on the ED frame for compatibility with Siemens Sentron and ITE systems. The breaker uses a thermal magnetic trip unit for precise overload and short-circuit protection, and is rated for 18kAIC at 480V. It is bolt-on style with load side lug terminals, making it suitable for a wide range of panel installations. The E43M020 is 50°C calibrated and features a non-interchangeable trip unit for added safety and reliability. This Siemens circuit breaker is ideal for applications requiring dependable circuit protection in demanding environments. The molded case design provides robust insulation and mechanical strength, while the thermal magnetic trip ensures accurate response to both overload and short-circuit conditions. The breaker is suitable for use in residential, commercial, and industrial installations, and is compatible with standard Siemens and ITE panelboards. \u003cul\u003e \u003cli\u003ePart Number: E43M020\u003c\/li\u003e \u003cli\u003eManufacturer: Siemens\u003c\/li\u003e \u003cli\u003eAmperage: 20A\u003c\/li\u003e \u003cli\u003eVoltage: 480V AC\u003c\/li\u003e \u003cli\u003ePoles: 3\u003c\/li\u003e \u003cli\u003eMounting Type: Bolt-On\u003c\/li\u003e \u003cli\u003eInterrupt Rating: 18kAIC @ 480V\u003c\/li\u003e \u003cli\u003eSeries\/Frame: ED Frame\u003c\/li\u003e \u003cli\u003eSeries: Sentron\u003c\/li\u003e \u003cli\u003eFrame Type: ED\u003c\/li\u003e \u003cli\u003eTrip Unit: Thermal Magnetic\u003c\/li\u003e \u003cli\u003eNon-Interchangeable Trip Unit\u003c\/li\u003e \u003cli\u003eLoad Side Lug Terminals\u003c\/li\u003e \u003cli\u003e50°C Calibrated\u003c\/li\u003e \u003cli\u003eWire Range: 14–10 AWG (Cu), 12–10 AWG (Al)\u003c\/li\u003e \u003cli\u003eDimensions: 3.00 x 6.4 x 3.92 in\u003c\/li\u003e \u003cli\u003eUL Listed\u003c\/li\u003e \u003cli\u003eCSA Certified\u003c\/li\u003e \u003c\/ul\u003e At \u003cb\u003eEssential Parts\u003c\/b\u003e, we offer \u003cb\u003efast shipping\u003c\/b\u003e, \u003cb\u003elowest price\u003c\/b\u003e, and \u003cb\u003eexpert support\u003c\/b\u003e to help you get the right product every time. \t\t\t\t\t\t\t\t\t\t\u003cbr\u003e                                          \t\t\t\t\t\t\t\t\t\t\u003ch3\u003e\u003cb\u003eSpecifications\u003c\/b\u003e\u003c\/h3\u003e \t\t\t\t\t\t\t\t\t\t\u003cul\u003e \t\t\t\t\t\t\t\t\t\t\t\u003cli\u003ePart Number: E43M020\u003c\/li\u003e                                             \u003cli\u003eManufacturer : Siemens\u003c\/li\u003e\n\u003cli\u003eCategory : Circuit Breaker\u003c\/li\u003e\n\u003cli\u003eItem Subcategory : Molded Case\u003c\/li\u003e\n\u003cli\u003eFamily : E Series\u003c\/li\u003e\n\u003cli\u003eVoltage : 480\u003c\/li\u003e\n\u003cli\u003eAmperage : 20\u003c\/li\u003e\n\u003cli\u003ePhase : 3\u003c\/li\u003e\n\u003cli\u003ePoles : 3\u003c\/li\u003e\n\u003cli\u003eAIC rating : 18kA@480V\u003c\/li\u003e\n\u003cli\u003eConnection : Bolt-On\u003c\/li\u003e\n\u003cli\u003eFunctions : LI - Long-Time and Instantaneous\u003c\/li\u003e\n\u003cli\u003eProtection : Thermal Magnetic\u003c\/li\u003e \t\t\t\t\t\t\t\t\t\t\u003c\/ul\u003e                                         \u003cbr\u003e                                         \u003ch3\u003e\u003cb\u003eProduct Data\u003c\/b\u003e\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eWeight : 7 \u003c\/li\u003e\u003c\/ul\u003e                                         \u003cbr\u003e                                          ","brand":"Siemens","offers":[{"title":"Re-Certified","offer_id":45126411976863,"sku":"E43M020-ReCert","price":139.86,"currency_code":"USD","in_stock":true}],"url":"https:\/\/essentialparts.com\/products\/e43m020-siemens-20a-480v-3-pole-molded-case-circuit-breaker-ed-frame-thermal-magnetic-trip","provider":"Essential Electric Supply","version":"1.0","type":"link"}
