Edison 80LET LET High Speed Semiconductor Fuse, 80 A, 240 VAC/150 VDC, 200 kA Interrupt, Round Body

Not surprisingly, this mounting type has found its use mainly, but not exclusively, in the United Kingdom and British Commonwealth countries. Also, North American manufacturers have begun to specify British style fuses (particularly in applications like UPS equipment with voltages of 240 V or less) due to their size, performance and cost advantages. The dimensions given in the BS88 Standard for high speed fuses are not physically interchangeable with industrial fuse standard.
