SIBA 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
I2t-values and high interrupting ratings. They are also the
most reliable under high cyclic loading conditions.
All fuses can be fitted with microswitches.
