Built on the SLD600A frame, this thermal magnetic circuit breaker is designed to provide dependable protection against overloads and short circuits while giving qualified technicians the flexibility to fine-tune trip settings for the specific needs of the system. Whether you're maintaining an existing facility, replacing a damaged breaker, or keeping critical equipment in service, the SHLD69400NGT is built to last and helps preserve the original design of compatible electrical equipment. One of the standout features of this breaker is its adjustable trip unit, which allows multiple protection settings to be configured for the application. Adjustable functions include continuous current setting, long-time delay, instantaneous setting, short-time pickup, short-time delay, short-time I²t pickup, ground fault pickup, and ground fault delay, making it easier to coordinate protection with other devices in the system. The breaker carries interrupting ratings of 35kA at 600VAC, 65kA at 480VAC, and 100kA at 240VAC, making it suitable for installations that require these fault-current capacities.\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\u003e400 Amp Molded Case Circuit Breaker:\u003c\/strong\u003e 400 Amp molded case circuit breaker.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThree-Pole Configuration:\u003c\/strong\u003e Three-pole configuration for three-phase power distribution.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThermal Magnetic Trip Mechanism:\u003c\/strong\u003e Thermal magnetic trip mechanism for overload and short-circuit protection.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSLD600A Frame:\u003c\/strong\u003e Built on the SLD600A frame.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSHLD6-A Breaker Type:\u003c\/strong\u003e SHLD6-A breaker type.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustable Trip Unit:\u003c\/strong\u003e Adjustable trip unit with Continuous Current Setting, Long Time Delay, Instantaneous Setting, Short Time Pickup, Short Time Delay, Short Time I²t Pickup, Ground Fault Pickup, and Ground Fault Delay.\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.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLug Terminals:\u003c\/strong\u003e Lug terminals 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 SHLD69400NGT\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:\u003c\/strong\u003e SLD600A\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 Mechanism:\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 400A\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\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\u003eThermal Magnetic Construction:\u003c\/strong\u003e Thermal magnetic molded case circuit breaker construction.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Designed for use in compatible commercial and industrial electrical distribution systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElectrical Ratings:\u003c\/strong\u003e Electrical ratings as specified by the manufacturer.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation Requirements:\u003c\/strong\u003e Always verify compatibility with your equipment and applicable local electrical codes before installation.\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 SHLD69400NGT is commonly used in commercial buildings, manufacturing facilities, institutional properties, and other industrial environments where a 400 amp, 3-pole molded case circuit breaker is required.
