Special Purpose Fuses Special Purpose Fuses American Fuses Form 600 A2Y, A6Y 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.
