FORM 600 FUSES
Ferraz Shawmut Form 600 fuses were the original current-limiting fuses,
pre-dating all the standards. Their 500V DC rating (through 600A) is a
useful feature for special applications. Form 600 fuses provide a high
degree of current limitation in AC and DC applications. Types 1 and 3
are dimensionally interchangeable with Class H and K fuses. Types 4 and 5
have unique rejection dimensions and are not interchangeable.
