This breaker features a thermal-magnetic trip unit for fast magnetic-trip protection against short circuits and time-delay-trip protection against overloads. The durable thermoset plastic housing ensures long-term reliability and resistance to dielectric breakdown after arcing. The breaker is color coded to indicate interrupting capacity and is suitable for use in compatible panelboards. Thomas \u0026amp; Betts TB390 breakers are classified for use where the available short circuit current is 10kA, 120\/240 VAC or less. The unique side-clip design allows for true common-trip operation in 120\/240 volt applications. Factory calibration after assembly ensures consistent performance. These breakers are switching duty rated and suitable for use with #1\/0 aluminum wire when used as a residential service main. \u003cul\u003e \u003cli\u003e3 Pole Configuration\u003c\/li\u003e \u003cli\u003e90 Amp Rating\u003c\/li\u003e \u003cli\u003e240 VAC Maximum Voltage\u003c\/li\u003e \u003cli\u003ePlug-In Mounting Style\u003c\/li\u003e \u003cli\u003e10,000 AIC Interrupt Rating\u003c\/li\u003e \u003cli\u003eThermal-Magnetic Trip Unit\u003c\/li\u003e \u003cli\u003eUL 489 Certified\u003c\/li\u003e \u003cli\u003eColor Coded Case for Interrupting Capacity\u003c\/li\u003e \u003cli\u003eSwitching Duty Rated\u003c\/li\u003e \u003cli\u003eSuitable for #1\/0 Aluminum Wire\u003c\/li\u003e \u003cli\u003eFactory Calibrated\u003c\/li\u003e \u003cli\u003eNon-Breakable Plastic Handle\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: TB390\u003c\/li\u003e                                             \u003cli\u003eManufacturer : Thomas \u0026amp; Betts\u003c\/li\u003e\n\u003cli\u003eBrand : Thomas \u0026amp; Betts\u003c\/li\u003e\n\u003cli\u003eCategory : Circuit Breaker\u003c\/li\u003e\n\u003cli\u003eItem Subcategory : Molded Case\u003c\/li\u003e\n\u003cli\u003eFamily : TB Series\u003c\/li\u003e\n\u003cli\u003eType : TB\u003c\/li\u003e\n\u003cli\u003eVoltage : 240\u003c\/li\u003e\n\u003cli\u003eAmperage : 90\u003c\/li\u003e\n\u003cli\u003ePhase : 3\u003c\/li\u003e\n\u003cli\u003ePoles : 3\u003c\/li\u003e\n\u003cli\u003eAIC rating : 10kA@240V\u003c\/li\u003e\n\u003cli\u003eConnection : Plug-In\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 : 2 \u003c\/li\u003e\u003c\/ul\u003e                                         \u003cbr\u003e                                          ","brand":"Thomas \u0026 Betts","offers":[{"title":"New","offer_id":44914125308063,"sku":"TB390-New","price":248.72,"currency_code":"USD","in_stock":true}],"url":"https:\/\/essentialparts.com\/products\/tb390-thomas-betts-3-pole-90-amp-240-vac-plug-in-circuit-breaker","provider":"Essential Electric Supply","version":"1.0","type":"link"}
