Built on the SJD 400-amp frame, this thermal magnetic circuit breaker is designed to help protect electrical equipment from overloads and short circuits while providing the flexibility of an adjustable SHJD6-A trip unit. Whether you're maintaining an existing commercial facility, servicing industrial equipment, or replacing a breaker in a power distribution system, this model offers the electrical ratings and adjustable protection settings needed to match many established applications.\u003c\/p\u003e\n\u003cp\u003eOne of the standout features of the SHJD69300NT is its range of adjustable trip functions. Qualified technicians can fine-tune the continuous current setting, long-time delay, instantaneous setting, short-time pickup, short-time delay, and short-time I²t pickup to coordinate protection with the rest of the electrical system. With interrupting ratings of 35kA at 600VAC, 65kA at 480VAC, and 100kA at 240VAC, this breaker is designed for demanding power distribution environments and is built to provide dependable service over the long term. Please note that lug terminals are not included and must be supplied separately if required for your installation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e300 Amp Continuous Current Rating:\u003c\/strong\u003e 300 Amp continuous current rating.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThree-Pole Design:\u003c\/strong\u003e Three-pole design for three-phase electrical systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThermal Magnetic Trip Mechanism:\u003c\/strong\u003e Thermal magnetic trip mechanism helps protect against overloads and short circuits.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSJD 400A Frame:\u003c\/strong\u003e SJD 400A frame with SHJD6-A adjustable trip unit.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustable Protection Functions Include:\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003eContinuous Current Setting\u003c\/li\u003e\n\u003cli\u003eLong-Time Delay\u003c\/li\u003e\n\u003cli\u003eInstantaneous Setting\u003c\/li\u003e\n\u003cli\u003eShort-Time Pickup\u003c\/li\u003e\n\u003cli\u003eShort-Time Delay\u003c\/li\u003e\n\u003cli\u003eShort-Time I²t Pickup\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Ratings:\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003e35kA @ 600VAC\u003c\/li\u003e\n\u003cli\u003e65kA @ 480VAC\u003c\/li\u003e\n\u003cli\u003e100kA @ 240VAC\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReplacement Compatibility:\u003c\/strong\u003e Designed as a form, fit, and functional replacement for compatible equipment.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilt to Last:\u003c\/strong\u003e Built to last for long-term use in commercial and industrial applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLug Terminals:\u003c\/strong\u003e Lug terminals are not included.\u003cbr\u003e\u003cstrong\u003e\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e SHJD69300NT\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCircuit Breaker Type:\u003c\/strong\u003e Molded Case Circuit Breaker\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e SHJD6-A\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame Size:\u003c\/strong\u003e SJD 400A Frame\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip Unit:\u003c\/strong\u003e Thermal Magnetic\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoles:\u003c\/strong\u003e 3\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage:\u003c\/strong\u003e 300A\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Rating:\u003c\/strong\u003e 35kA @ 600VAC; 65kA @ 480VAC; 100kA @ 240VAC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003eHeight: 11.0 in.\u003c\/li\u003e\n\u003cli\u003eWidth: 7.5 in.\u003c\/li\u003e\n\u003cli\u003eDepth: 4.0 in.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustable Functions:\u003c\/strong\u003e Continuous Current Setting, Long-Time Delay, Instantaneous Setting, Short-Time Pickup, Short-Time Delay, Short-Time I²t Pickup\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLug Terminals:\u003c\/strong\u003e Not Included\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eMaterial Compliance and Certifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Family Specifications:\u003c\/strong\u003e The SHJD69300NT is manufactured for use in compatible electrical distribution equipment and is designed to meet the original electrical and mechanical specifications of its product family.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation Requirements:\u003c\/strong\u003e Installation and maintenance should always be performed by qualified electrical personnel in accordance with applicable electrical codes, manufacturer recommendations, and local regulations.\u003cbr\u003e\u003cstrong\u003e\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eWhere It Works Best\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThe SHJD69300NT is commonly used in commercial buildings, industrial facilities, manufacturing plants, distribution equipment, switchboards, panelboards, and feeder circuits where a 300A, 3-pole thermal magnetic molded case circuit breaker is required.
