In real-world use, this breaker is typically found in main service switchboards, industrial distribution equipment, and large commercial electrical systems running on 480V and 600V AC power.\u003c\/p\u003e\n\u003cp\u003eIn practice, this is the type of breaker you’ll see in established electrical infrastructure rather than small or standalone setups. It’s commonly used in Siemens ND frame assemblies, where maintaining system compatibility is important during replacement or maintenance work. Instead of redesigning a panel, this breaker fits into existing equipment to help keep systems running the way they were originally configured.\u003c\/p\u003e\n\u003cp\u003eThis unit is 40°C rated and comes with line and load side lugs (TA4N8500), helping simplify installation in compatible Siemens equipment. It accepts 250–500 kcmil copper or aluminum conductors, making it suitable for larger feeder applications where heavier wiring is required. The 3-pole design ensures all phases disconnect together during a fault, which is standard in three-phase distribution systems.\u003c\/p\u003e\n\u003cp\u003eAt its core, the CND63B100 is used to keep existing Siemens ND frame systems operating as intended — matching form, fit, and function in established electrical infrastructure.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e1000 Amp, 3-pole Siemens ND frame molded case circuit breaker\u003c\/li\u003e\n\u003cli\u003eDesigned for Siemens SENTRON power distribution systems\u003c\/li\u003e\n\u003cli\u003eThermal-magnetic trip unit for overload and short-circuit protection\u003c\/li\u003e\n\u003cli\u003eCurrent-limiting design for controlled fault response\u003c\/li\u003e\n\u003cli\u003eHigh interrupting ratings: 100kA @ 480V, 65kA @ 600V\u003c\/li\u003e\n\u003cli\u003eIncludes line and load side lugs (TA4N8500)\u003c\/li\u003e\n\u003cli\u003eAccepts 250–500 kcmil Cu\/Al conductors\u003c\/li\u003e\n\u003cli\u003e40°C rated for defined operating conditions\u003c\/li\u003e\n\u003cli\u003e3-pole simultaneous disconnect for three-phase systems\u003c\/li\u003e\n\u003cli\u003eUsed in feeder and main service applications\u003c\/li\u003e\n\u003cli\u003eBuilt for compatibility with existing ND frame installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCatalog Number:\u003c\/strong\u003e CND63B100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Molded Case Circuit Breaker\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame Type:\u003c\/strong\u003e ND Frame\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Rating:\u003c\/strong\u003e 1000 Amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoles:\u003c\/strong\u003e 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating:\u003c\/strong\u003e 600V AC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Rating:\u003c\/strong\u003e 100kA @ 480V; 65kA @ 600V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip Unit:\u003c\/strong\u003e Thermal-Magnetic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Rating:\u003c\/strong\u003e 40°C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConductor Range:\u003c\/strong\u003e 250–500 kcmil Cu\/Al\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded:\u003c\/strong\u003e Line and load side lugs (TA4N8500)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 9 in W x 16 in H x 6 in D\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNet Weight:\u003c\/strong\u003e 54 lb\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eMaterial Compliance and Certifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe CND63B100 Siemens SENTRON breaker is designed to meet UL 489 and IEC 60947-2 standards for industrial molded case circuit breakers used in electrical distribution systems.
