Built on the SLD600A frame, this 3-pole thermal magnetic circuit breaker is designed to provide a form, fit, and functional replacement for compatible equipment already in service. Its adjustable trip unit allows electricians and maintenance professionals to tailor protection settings to the needs of the installation, making it easier to coordinate system protection while helping guard against overloads, short circuits, and ground faults. The SHLD69300G includes adjustable settings for continuous current, long-time delay, instantaneous trip, ground fault pickup, and ground fault delay, giving users greater flexibility when configuring protection for connected equipment. With interrupting capacities rated at 35kA at 600VAC, 65kA at 480VAC, and 100kA at 240VAC, this breaker is well suited for demanding power distribution systems found in manufacturing facilities, commercial buildings, institutional properties, and other industrial environments. Built to last, it offers a dependable solution for maintaining existing electrical systems without changing equipment layouts or mounting configurations.\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 Current Rating:\u003c\/strong\u003e 300 Amp current rating for commercial and industrial power distribution.\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\u003eAdjustable Trip Unit:\u003c\/strong\u003e Adjustable trip unit includes Continuous Current Setting, Long Time Delay, Instantaneous Setting, Ground Fault Pick Up, and Ground Fault Delay.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSLD600A Frame:\u003c\/strong\u003e SLD600A frame for compatibility with designated equipment.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Ratings:\u003c\/strong\u003e 35kA @ 600VAC, 65kA @ 480VAC, and 100kA @ 240VAC.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilt to Last:\u003c\/strong\u003e Built to last for long-term service in compatible electrical systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReplacement Design:\u003c\/strong\u003e Designed as a form, fit, and functional replacement for compatible legacy installations.\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 SHLD69300G\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e SHLD6-A\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame Size:\u003c\/strong\u003e SLD600A Frame\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\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 300 Amps\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\u003eAdjustable Functions:\u003c\/strong\u003e Continuous Current Setting, Long Time Delay, Instantaneous Setting, Ground Fault Pick Up, Ground Fault Delay\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\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\u003eCommercial and Industrial Use:\u003c\/strong\u003e Manufactured for use in commercial and industrial electrical distribution systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSHLD6-A Platform:\u003c\/strong\u003e Designed to meet the electrical ratings and performance characteristics associated with the SHLD6-A platform.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Capacities:\u003c\/strong\u003e Interrupting capacities are specified for 240VAC, 480VAC, and 600VAC applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation Requirements:\u003c\/strong\u003e Installation should be performed in accordance with applicable electrical codes and manufacturer recommendations.\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 SHLD69300G is commonly installed in commercial facilities, manufacturing plants, industrial operations, institutional buildings, and other large electrical distribution systems where a 300 Amp, 3-pole molded case circuit breaker is required.
