*西霸熔断器
SIBA高压熔断器由并联的纯银熔体构成，熔体狭窄部位的设计与生产方法保证了时间—电流特性曲线的误差极小。熔体缠绕在星状陶瓷骨架上，其末端以电阻焊焊接到陶瓷骨架的镀银铜盖帽（内帽）上，再以点焊方式将此帽固定在zui外面的镀银铜帽内侧，外铜帽用机械方法固定在内外上釉的陶瓷套管上，再用耐久弹性密封剂密封。这种密封方法已在过去数十年现场有效实践中得到证明，保证密封，不会受潮SIBA Miniature Fuses

SIBA ultra-rapid knife blade contact fuses type NH are available in many different sizesour voltage ratings. They follow DIN/VDE -IEC standardcan be fitted in open fusebases. Usage in fuse bases or switches requires the comparison of the power loss of the fuse with the power acceptance of the base or switch.
All SIBA type NH-fuses are available with either integral blown fuse indicator or a separay fitted trip indicator fuse for microswitch operation.
Class: aR/gR
Sizes: 000 / 00 / 0 / 1 / 23
Voltage ratings: AC 500 V - 2000 V
Current ratings: 16 A up to 800 A
SIBA square body fuses type SQB are available in 3 different body sizes. Each size is available in variousmounting styles for global applications. Variety in bodysizes, mounting styleamp ratings allow the greatestflexibility in equipment design.
SIBA SQB fuses provide superior engineering for theprotection of today’s power semiconductors. Thesilicated process together with special shapeformof the pure silver melting elements give excellent resultsof low I2t-valueshigh interrupting ratings. And theyare the most reliable under high cycling load conditions.
All fuses can be fitted with microswitches.
