0997010.WXN 产品概述

一、产品简介

0997010.WXN 是 Littelfuse(美国力特)出品的一款刀片式快速熔断保险丝(Blade Fuse,Fast Acting),额定电压 58V、额定电流 10A。该产品采用标准刀片尺寸(10.9 × 3.8 mm),便于与常见的ATC/ATO型保险丝座和快速接插(Quick Connect)端子配合使用。设计用于在短路或过载时迅速切断电路,以保护下游敏感器件和布线系统。

品牌:Littelfuse(美国力特) 类型:刀片式、快速熔断(Fast Acting) 刀片尺寸:10.9 × 3.8 mm(适配标准ATC/ATO插座)

二、主要技术参数

  • 额定电压:58 V DC
  • 额定电流:10 A
  • 分断能力(中断容量):1 kA @ 58 V
  • 电压降(典型值):108 mV(额定电流下)
  • 标称冷电阻:7.42 mΩ
  • 熔断能量(I²t):93 A²s(指示熔断释放能量)
  • 工作温度范围:-40 ℃ ~ +125 ℃
  • 接口形式:刀片式快速接触,便于插拔与更换

三、性能要点与电气特性

  • 快速熔断特性:该保险丝为快断型,响应迅速,能在短路发生时迅速开断,减少对受保护电路的热冲击和能量冲击,适用于对过流响应速度要求较高的场合。
  • 中断能力:1 kA 的分断能力表明在额定电压下可安全切断最高约 1 kA 的短路电流,适用于中低故障电流水平的直流系统。在更高故障电流环境下建议选择分断能力更高的型号或并联保护方案。
  • 电压降与功耗:在 10 A 工作电流下典型电压降为 108 mV,对应功耗约 1.08 W(P = V × I)。使用时应考虑该功耗引起的发热,并确保保险丝及周边结构能承受工作温升。
  • I²t 值:93 A²s 表征在故障清除过程中保险丝释放的能量,值越小意味着对下游设备的能量让渡越少,保护性能越积极。对敏感电子模块有较好保护效果。
  • 环境适应性:-40 ℃ 至 +125 ℃ 的宽温范围适合多数工业、通信及车辆电子环境,但在接近上限温度时仍建议按制造商推荐进行电流降额。

四、典型应用场景

  • 48V/58V 通信电源与交换设备的短路保护。
  • 车辆(商用车、特殊车辆)与船用直流配电系统中的回路保护(需核对系统电压与标准兼容性)。
  • 储能与逆变器前端对电池/直流母线的保护(适用于故障电流在分断能力范围内的场景)。
  • 工业自动化控制电源、传感器电源及小功率驱动模块的过流保护。
  • 任何需要快速断开以保护敏感电子器件的低压直流环境。

五、选型与安装建议

  • 确认工作电压与额定电流:不要超过 58 V 和 10 A 的额定值;若持续工作中存在高环境温度,应考虑对保险丝电流进行适当降额。
  • 对比分断能力:确认系统可能出现的最大短路电流不超过 1 kA,若有可能超过,应选择分断能力更高的产品或在前端加装更大容量保护器件。
  • 考虑熔断特性:快断型适用于保护敏感负载,但若电路中存在较大启动电流(电机、充电电容等),建议选用延时(慢熔)型。
  • 热管理:保证保险丝周围有足够散热空间;在并联或密集安装场景下注意热累积。
  • 机械安装:使用与标准 10.9 × 3.8 mm 刀片配套的保险丝座或快速接线端子,确保接触良好、无松动,以免接触电阻升高造成额外发热。

六、注意事项与合规性

  • 更换必须使用相同规格与熔断特性的保险丝,避免用高于额定电流的元件取代。
  • 在有严格安全与认证要求(如船用、汽车 OEM 或通信机房)时,核实具体型号的认证与资料(如是否符合 RoHS、UL/CSA 等)后再做选型与采购。
  • 维护时断电操作,避免带电更换导致电弧或二次损坏。

七、总结

0997010.WXN 是一款面向直流低压系统的刀片式快速熔断保险丝,凭借 Littelfuse 的品牌与设计,在需要快速断开、保护敏感电子设备的场景中表现可靠。其 58 V/10 A 的额定值、1 kA 的分断能力以及标准刀片尺寸,使其在通信电源、48V/58V 直流配电、工业控制和部分车用/船用场合具有良好的适配性。选型时应注意与系统短路电流水平、环境温度及负载特性匹配,必要时参考完整产品数据手册或联系供应商获取认证与安装细节。
