Engineered as a Class L time‑delay, current‑limiting fuse rated at 800 A, this model offers exceptional fault interruption performance — including a 300 kA interrupting capacity at 600 V AC and 100 kA at 300 V DC. Its design features bolted‑blade end connections for secure, reliable contact in heavy duty applications, and a compact cartridge size (8.63″ length × 2.53″ width × 2.53″ height) that fits tight panel configurations. With a minimum response time of about four seconds at 500% of rated current, it disconnects fault currents swiftly to safeguard downstream equipment and maintain operational confidence.\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\u003eHigh interrupting capacity:\u003c\/strong\u003e Designed to handle major fault events with ease (300 kA at 600 V AC \/ 100 kA at 300 V DC), making it suitable for rugged applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTime‑delay \/ current‑limiting performance:\u003c\/strong\u003e Allows momentary startup currents or transient peaks, yet reacts quickly under sustained over‑current, offering both protection and flexibility.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBolted blade end connections:\u003c\/strong\u003e Ensures a strong, stable electrical interface in heavy‑duty panelboards, feeders and switchgear environments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact cartridge form‑factor:\u003c\/strong\u003e At under 9″ in length and approx. 2.5″ in diameter, it is designed for installation in spaces where larger fuses may not fit comfortably.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNon‑indicating model:\u003c\/strong\u003e For setups where fuse status indicators are not required, this version offers a cost‑effective and durable solution.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptimized for heavy systems:\u003c\/strong\u003e The fuse features pure silver links, premium arc‑quenching filler, and high‑pressure O‑ring seals — all ensuring low heat, high reliability and extended system life.\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\u003eAmperage Rating:\u003c\/strong\u003e 800 A\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating:\u003c\/strong\u003e 600 V AC \/ 300 V DC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Rating:\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003e300 kA AC at 600 V\u003c\/li\u003e\n\u003cli\u003e100 kA DC at 300 V\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResponse Time:\u003c\/strong\u003e Approximately 4 seconds at 500% of rated current\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003eLength: 8.63 inches\u003c\/li\u003e\n\u003cli\u003eWidth: 2.53 inches\u003c\/li\u003e\n\u003cli\u003eHeight: 2.53 inches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e Approximately 3.8 lb (per datasheet)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection:\u003c\/strong\u003e Bolted‑blade end on both ends (bolted blade x bolted blade)\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\u003eRoHS Compliant:\u003c\/strong\u003e Meets international standards restricting hazardous substances in electrical products.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCE Marked:\u003c\/strong\u003e Meets European Union safety, health and environmental standards.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUL Listed \u0026amp; CSA Certified:\u003c\/strong\u003e Built to recognized North American safety standards for Class L fuses.\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\u003eThis fuse is an excellent match for high‑demand applications including large distribution switchboards, heavy machinery feeders, industrial control panels, and critical infrastructure that cannot afford downtime.
