2021年5月6日，工业技术制造公司LITTELFUSE于芝加哥宣布发布电涌保护器（SPD）选择指南，该指南依据所提供的规格要求，给出SPD尺寸大小选择建议，为系统提供最高级别的保护。

电涌保护器的尺寸必须正确。如果尺寸太小，系统可能会受到暂时的过电压影响，并导致SPD的预期寿命缩短。如果尺寸太大，则可能会损坏设备。

Littelfuse高级市场经理Debra Jayson表示：“该易于使用的选择指南为客户提供了一个交互式计算器，可以快速提供合适的SPD尺寸，从而为系统提供最大的电涌保护。”

“输入规格后，指南将根据所提供的参数计算出最佳配置，并通过数据表和其他技术资源的链接，给出所推荐的SPD产品的有关信息。”

《电涌保护设备选择指南》将根据以下变量确定特定系统的最优最大连续工作电压（MCOV）大小：

线间电压

导体数量

接地或不接地

是否有零线

是否安装SPD

是否需要远程指示
