The time-delay characteristic allows the fuse to tolerate brief inrush currents during power-on without blowing, then protect against sustained overcurrent faults.\u003c\/p\u003e\n\u003cp\u003eUsed in professional audio amplifiers, studio monitoring equipment, mixing desks, effects units, and other sensitive electronics where a standard fast-blow fuse would nuisance-trip on startup surge, the slow blow rating provides circuit protection without false triggering. The 5 x 20mm format fits standard cartridge fuse holders in mains input stages and power supply sections across European and international audio and electronic devices.\u003c\/p\u003e\n\u003cp\u003eThe glass tube construction allows visual inspection of the internal fusible element — a blown fuse shows a visible break in the thin wire element inside the tube. The 160mA rating suits low-power signal-processing equipment and devices drawing less than 40W on 250V mains. IEC approval confirms compliance with international safety standards for fuse performance and rating.\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does 'slow blow' mean?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA slow blow (time-delay) fuse tolerates brief overcurrent conditions such as inrush surge when equipment powers on, but will blow if the overcurrent is sustained for more than a fraction of a second. This prevents nuisance blowing in devices with high startup current draw.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat devices use 160mA fuses?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eLow-current audio equipment, studio monitoring amplifiers, effects processors, mixers, and precision electronic devices drawing less than 40W on 250V mains typically use 160mA-rated fuses in their power supply protection stages.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAre these fuses interchangeable with fast-blow fuses?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003ePhysically they fit the same 5 x 20mm fuse holders, but functionally they are not interchangeable. Replacing a slow blow fuse with a fast blow fuse may result in nuisance blowing during power-on. Always replace with the same rating and type specified by the equipment manufacturer.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow can I tell if the fuse has blown?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe glass tube construction allows visual inspection. A blown fuse will show a visible break in the thin internal wire element, and often a dark discolouration or carbon deposit on the inside of the glass.\u003c\/p\u003e","brand":"AVSL","offers":[{"title":"Default Title","offer_id":45313484718347,"sku":"787.002UK","price":1.49,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/787002UK_LB1_5a3ae9c2-1874-403f-8397-4774a07dc2e1.jpg?v=1715194096","url":"https:\/\/niori.co.uk\/products\/mercury-5-x-20mm-t160ma-slow-blow-fuses-250v","provider":"Niori","version":"1.0","type":"link"}
