To ensure optimal performance in high-power applications, this kit provides a \u003cstrong\u003ematched set of two thyristors\u003c\/strong\u003e, factory-tested to maintain identical switching characteristics. This matching is critical for 800A current applications where balanced load sharing prevents component overheating and premature system failure. With a total net weight of approximately \u003cstrong\u003e1.15 kg (2.54 lbs)\u003c\/strong\u003e, this kit is an essential spare part for maintaining the integrity of medium voltage power conversion modules.\n\u003c\/p\u003e\n\n\u003ch2 style=\"color: #2c3e50; font-size: 24px;\"\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; margin: 20px 0;\"\u003e\n  \u003cthead\u003e\n    \u003ctr style=\"background-color: #f8f9fa;\"\u003e\n      \u003cth style=\"border: 1px solid #dee2e6; padding: 12px; text-align: left;\"\u003eParameter\u003c\/th\u003e\n      \u003cth style=\"border: 1px solid #dee2e6; padding: 12px; text-align: left;\"\u003eSpecification\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #dee2e6; padding: 12px;\"\u003eBrand\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #dee2e6; padding: 12px;\"\u003e\u003cstrong\u003eAllen-Bradley\u003c\/strong\u003e\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #dee2e6; padding: 12px;\"\u003eModel Number\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #dee2e6; padding: 12px;\"\u003e\u003cstrong\u003e81001-450-52-R\u003c\/strong\u003e\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #dee2e6; padding: 12px;\"\u003eCurrent Rating\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #dee2e6; padding: 12px;\"\u003e800 Amperes\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #dee2e6; padding: 12px;\"\u003eConfiguration\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #dee2e6; padding: 12px;\"\u003eMatched Set of 2 Thyristors\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #dee2e6; padding: 12px;\"\u003e\u003cstrong\u003eNet Weight\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #dee2e6; padding: 12px;\"\u003e\u003cstrong\u003e1.15 kg (2.54 lbs)\u003c\/strong\u003e\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #dee2e6; padding: 12px;\"\u003eCompatibility\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #dee2e6; padding: 12px;\"\u003ePowerFlex Series Drives\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2 style=\"color: #2c3e50; font-size: 24px;\"\u003eEngineering Advantages\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli style=\"margin-bottom: 10px;\"\u003e\n\u003cstrong\u003ePrecise Matching:\u003c\/strong\u003e The \u003cstrong\u003e81001-450-52-R\u003c\/strong\u003e kit eliminates the risks associated with mixing unmatched semiconductors, ensuring uniform voltage distribution across the power module.\u003c\/li\u003e\n  \u003cli style=\"margin-bottom: 10px;\"\u003e\n\u003cstrong\u003eHigh Power Density:\u003c\/strong\u003e Engineered for 800A operation, these thyristors provide superior thermal management and low conduction losses in demanding industrial environments.\u003c\/li\u003e\n  \u003cli style=\"margin-bottom: 10px;\"\u003e\n\u003cstrong\u003eService Readiness:\u003c\/strong\u003e Despite the heavy-duty electrical rating, the \u003cstrong\u003e1.15 kg\u003c\/strong\u003e total weight makes this kit highly portable for field technicians and emergency repairs.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2 style=\"color: #2c3e50; font-size: 24px;\"\u003eInstallation \u0026amp; Maintenance\u003c\/h2\u003e\n\u003cp\u003e\n  When installing the \u003cstrong\u003eAllen-Bradley 81001-450-52-R\u003c\/strong\u003e, it is vital to apply the correct clamping force as specified in the included service documentation.
