SIBA URS square body fuses type SQB are available in four different body sizes. Each size is available in various mounting styles for global applications. Variety in body sizes, mounting style and amp ratings allow maximum flexibility in equipment design.

SIBA SQB fuses provide superior engineering for the protection of today’s power semiconductors. The silicated process, together with special shape and form of the pure silver melting elements, give excellent results of low I2 t-values and high interrupting ratings. They are also the most reliable under high cyclic loading conditions. All fuses can be fitted with microswitches.
