Rated at 300 amps with a 200 kA interrupting capacity at 600 VAC, this very fast-acting fuse is commonly used in commercial and industrial power distribution equipment where protecting sensitive components is critical. Its current-limiting design helps reduce the amount of damaging fault energy that reaches downstream equipment, extending the life of connected systems and minimizing unexpected downtime. This fuse features a knife-blade style design for a secure fit and dependable electrical contact. The compact size also makes it a practical option for installations with limited panel space. Because it reacts quickly during fault conditions, the TJS300 is often used in systems with transformers, motor controls, UPS equipment, and other applications where rapid circuit protection is important. The non-indicating construction keeps the design simple while still delivering reliable performance in demanding environments.\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 Class T fuse for commercial and industrial applications:\u003c\/strong\u003e Designed for dependable overcurrent protection in demanding electrical systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVery Fast-Acting Response:\u003c\/strong\u003e Helps protect equipment from damaging fault currents by reacting quickly during overload and short-circuit conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent-Limiting Design:\u003c\/strong\u003e Reduces thermal and mechanical stress on downstream components by limiting damaging fault energy.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh Interrupting Capacity:\u003c\/strong\u003e Rated at 200 kA at 600VAC for use in systems with high available fault current.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKnife-Blade Construction:\u003c\/strong\u003e Provides a secure installation and dependable electrical contact.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact Footprint:\u003c\/strong\u003e Works well in tight electrical enclosures and limited panel spaces.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Performance Protection:\u003c\/strong\u003e Designed for reliable overcurrent protection of sensitive electrical equipment and power distribution systems.\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 TJS300\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Class T Fuse\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\u003eVoltage Rating:\u003c\/strong\u003e 600VAC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Rating:\u003c\/strong\u003e 200 kA @ 600VAC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Characteristics:\u003c\/strong\u003e Very Fast-Acting, Current-Limiting\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStyle:\u003c\/strong\u003e Knife-Blade\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndication:\u003c\/strong\u003e Non-Indicating\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003eHeight: 3.625 in\u003c\/li\u003e\n\u003cli\u003eWidth: 1.593 in\u003c\/li\u003e\n\u003cli\u003eDepth: 1.593 in\u003c\/li\u003e\n\u003c\/ul\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\u003eIndustry Applications:\u003c\/strong\u003e The TJS300 fuse is manufactured for use in high-interrupting-capacity electrical protection applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass T Standards:\u003c\/strong\u003e It is designed to align with common industry requirements for Class T current-limiting fuses used in commercial and industrial power systems.\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 TJS300 is commonly used in switchboards and panelboards, motor control centers, industrial machinery and manufacturing equipment, UPS and backup power systems, transformer protection applications, commercial electrical distribution systems, and facilities with high available fault current levels.
