Rated for 45 amps, this time-delay fuse helps protect the circuits and equipment from overloads and short circuits while still handling the temporary surge that happens when motors or HVAC equipment start up. Instead of opening too quickly during normal startup conditions, it’s designed to allow those brief current spikes to pass, helping reduce unnecessary downtime. Its current-limiting design helps reduce the amount of fault energy flowing through the system during a short circuit, helping protect connected equipment from additional damage. With a 200 kA interrupting rating at 250 VAC, the TR45R is commonly used in commercial and industrial applications where dependable circuit protection matters. The compact cartridge-style body also makes it easier to fit into existing electrical setups without taking up much space. Whether you’re replacing a fuse in a motor control panel or maintaining power distribution equipment, the TR45R offers straightforward, dependable performance for demanding electrical 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\u003e45 amp Class R fuse for circuit protection:\u003c\/strong\u003e Designed to help protect circuits and connected equipment in commercial and industrial electrical systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTime-delay design:\u003c\/strong\u003e Helps avoid unnecessary fuse openings during equipment startup by allowing temporary surge currents to pass during normal motor or HVAC startup conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent-limiting performance:\u003c\/strong\u003e Helps reduce damage during fault conditions by limiting the amount of fault energy flowing through the electrical system.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact cartridge-style body:\u003c\/strong\u003e Makes installation easier in existing electrical setups without taking up much space.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh interrupting rating:\u003c\/strong\u003e Rated at 200 kA at 250 VAC for dependable protection in demanding electrical environments.\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 TR45R\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Class R Fuse\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStyle:\u003c\/strong\u003e Cartridge Style\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\u003eTime Delay:\u003c\/strong\u003e Yes\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent-Limiting:\u003c\/strong\u003e Yes\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage:\u003c\/strong\u003e 45 Amps\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eA.I.C.
