{"product_id":"fwh-100b-bussman","title":"FWH-100B-BUSSMANN","description":"\u003cp\u003eThe FWH-100B-BUSSMANN is a high-speed semiconductor protection fuse from Eaton's Bussmann series, rated at 100 amperes and engineered specifically for the protection of power semiconductor devices including IGBTs, thyristors, MOSFETs, and rectifier diodes. Unlike conventional branch-circuit fuses, the FWH-B series features extremely low I²t let-through values and rapid arc interruption, ensuring that downstream semiconductor junctions are protected before thermal damage can propagate through the device. This makes the FWH-100B an industry-standard choice wherever solid-state power devices must be safeguarded against fault conditions.\u003c\/p\u003e\u003cp\u003eThe FWH-100B-BUSSMANN is widely deployed in industrial variable frequency drives (VFDs), DC bus protection circuits, UPS systems, soft starters, welding inverters, and rectifier panels. Power electronics engineers rely on this fuse series in both OEM design and field replacement scenarios where semiconductor-grade overcurrent protection is non-negotiable. Its compact form factor and standardized mounting dimensions make it a drop-in solution for panel upgrades, drive repairs, and legacy system maintenance across manufacturing, oil and gas, marine, and utility infrastructure environments.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQuick Reference: FWH-100B-BUSSMANN\u003c\/strong\u003e\u003c\/p\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eFWH-100B-BUSSMANN\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eManufacturer\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eEaton \/ Bussmann Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eType\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eFast-Acting Semiconductor Protection Fuse\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCurrent Rating\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e100A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e500V AC \/ 500V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eAvailability\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eIn Stock — Same-Day Shipping Available\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCondition\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eNew OEM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003cp\u003e\u003cstrong\u003eKey Features of the FWH-100B-BUSSMANN:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eUltra-fast current-limiting action with exceptionally low I²t let-through energy, minimizing stress on downstream semiconductor junctions during fault events\u003c\/li\u003e\n\u003cli\u003e100A continuous current rating with 500V AC\/DC interrupting capability suited for medium-power drive and rectifier topologies\u003c\/li\u003e\n\u003cli\u003eKnife-blade (bolted) terminal construction ensures low-resistance, vibration-resistant connections in demanding industrial panel environments\u003c\/li\u003e\n\u003cli\u003eHigh interrupting rating provides reliable arc quenching under short-circuit conditions without case rupture or collateral damage\u003c\/li\u003e\n\u003cli\u003eCompact, standardized body dimensions compatible with common DIN-rail and panel-mount fuseholders used across major drive and rectifier OEM platforms\u003c\/li\u003e\n\u003cli\u003eCompliant with UL 248-13 and IEC 60269-4 semiconductor fuse standards for global installation and certification requirements\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eThe FWH-100B-BUSSMANN has historically experienced long lead times through traditional distribution channels, and certain configurations have been subject to allocation or phase-out as OEM drive platforms evolve. Maintenance teams supporting legacy VFDs, rectifier cabinets, or uninterruptible power supplies often encounter extended wait times just when an unplanned outage demands immediate action. ATI Accurate Technology maintains strategic inventory of hard-to-find and long-lead-time semiconductor protection components specifically to bridge this gap, keeping critical operations running without costly production delays.\u003c\/p\u003e\u003cp\u003eATI Accurate Technology is your stocking source for the FWH-100B-BUSSMANN, shipping same day on orders placed before 5PM EST from our Palmetto, Florida facility.
