SIBA Fuses for Semiconductor Protection
North American and European Standard Type SQB Sizes 1, 2 and 3
SIBA square body fuses type SQB are available in 3 different body sizes. Each size is available in various mounting styles for global applications. Variety in body sizes, mounting style and amp ratings allow the greatest flexibility in equipment design.

SIBA SQB fuses provide superior engineering for the protection of todays power semiconductors. The silicated process together with special shape and form of the pure silver melting elements give excellent results of low I2t-values and high interrupting ratings. All fuses can be fitted with microswitches.
