What does Al on a fuse mean?
The number and the A (may be mA) is the amp rating of the fuse. The L denotes that it is a low breaking capacity or glass fuse (H is High breaking capacity and is usually a ceramic package). Taking the example above a T2AL250V fuse is a 2 Amp, Time Delay glass fuse rated for 250 Volts.
What does the T stand for on a fuse?
T = slow burn fuse. F = fast acting fuse. TT = very slow burn fuse. FF = very fast acting fuse.
What is G Si fuse?
GSI have been a distributor of fuses for over 20 years. Supplying circuit protection to OEM’s, PCB manufacturers, electrical contractors. We supply fuses, fuse holders, fast acting fuses, slow blow fuses, industrial fuses and many more.
What does 250vp mean on a fuse?
H = High rupture. This means that there’s a risk that the fuse may need to blow during a significant overload and so the fuse body is ceramic instead of glass to contain the rupture without shattering. 250V = Max working voltage. P = RoHS compliant (lead free)
What are standard fuse sizes?
Standard sizes for fuses and fixed trip circuit breakers, per 240.6, are 15, 20, 25, 30, 35, 40, 45, 50, 60, 70, 80, 90, 100, 110, 125, 150, 175, 200, 225, 250, 300, 350, 400, 450, 500, 600, 700, 800, 1000, 1200, 1600, 2000, 2500, 3000, 4000 5000, and 6000 amps.
What are glass fuses used for?
Glass and ceramic tube fuses are often used to protect appliances and consumer electronics. As electronic equipment becomes smaller, the circuits and components become more delicate and easily damaged. Fuses are the preferred method of protection due to their accuracy, small size and reliability.
Are f1al250v fuses made in China?
Four of the fuses are marked as F1AL250V. One of the five fuses is not marked on either end, who knows what it is. I suspect these were made in China by a knock off company. I spent more money on these fuses because I wanted the name brand.
What is a high speed fuse used for?
The aR high speed fuses are intended for short-circuit protection of semiconductors found in low-voltage electronic devices, such as frequency inverters and soft-starters� Manufactured and tested according to IEC 60269-4 and UL 248-13 standards,
What do the markings on fuses mean?
Fuse Breaking Capacity Markings Note: Many small cartridge fuses will have additional markings stamped on the end caps. These are usually either; a series number, a part number, or product approval markings (refer table 3 below). If you are unable to identify the fuse, please contact us.
