The slow blow (time-delay) design allows short inrush currents during equipment start-up without blowing the fuse, while still providing overcurrent protection if a sustained fault develops.\u003c\/p\u003e\n\u003cp\u003eDesigned for low-current circuits in audio equipment, lighting controllers, small appliances and electronic devices where motors, transformers or capacitive loads create momentary current spikes on power-up. The 6 x 32mm form factor fits standard fuse holders used across consumer electronics, automotive applications and industrial control panels. The glass tube allows visual inspection of the fuse element to confirm whether the fuse has blown.\u003c\/p\u003e\n\u003cp\u003eEach fuse is IEC approved and carries nickel-plated brass end caps that resist corrosion and maintain consistent contact pressure in the holder. The slow blow characteristic typically tolerates inrush currents up to 10x the rated 3.15A for short periods (measured in milliseconds), making it suitable for circuits where nuisance blowing with fast-acting fuses is a recurring problem.\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's the difference between slow blow and fast-acting fuses?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eSlow blow (time-delay) fuses tolerate short current surges without breaking the circuit, making them suitable for equipment with motors or transformers that draw higher current on start-up. Fast-acting fuses blow immediately when the rated current is exceeded, providing faster protection for sensitive electronics but less tolerance for inrush.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat voltage rating does the fuse carry?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe T3.15A is rated at 250V. This is the maximum voltage the fuse can safely interrupt if a fault occurs. Using it in circuits above 250V risks arc-over and failure to interrupt the fault.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow many fuses are in a pack?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eMercury 6 x 32mm fuses are typically supplied in packs of 10.

However, confirm the amperage requirement of the circuit before fitting — a 3.15A fuse is only suitable for low-draw circuits like interior lights or control modules.\u003c\/p\u003e","brand":"AVSL","offers":[{"title":"Default Title","offer_id":45313487601931,"sku":"787.142UK","price":1.49,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/787142UK_LB1_8e359d32-b89d-4dc6-afa2-375f25371ec5.jpg?v=1715194196","url":"https:\/\/niori.co.uk\/products\/mercury-6-x-32mm-t3-15a-slow-blow-fuses-glass-tube-pack-of-10","provider":"Niori","version":"1.0","type":"link"}
