请注意:此版本的所有临时修订版将在您购买时提供。UL 1416的要求适用于无线电和电视类设备中使用的超温保护器和过电流保护器，适用于以下情况: 在设备由最大20 a分支电路供电的情况下，依靠保护器来限制功率、电流或两者。遵守这些规定 要求不应被视为表明最终使用产品中可接受过电流或超温保护器。这些要求涵盖的任何保护装置在任何特定组件、装置或器具中的可接受性取决于持续使用的条件 这在实际服务中很普遍。因此，对于特定应用，保护器可能会受到应用中组件、设备或装置的要求的影响 问题，并且可能有必要使用除这些要求中规定的特性以外的保护装置。这些要求不适用于热切断装置（单操作可熔型超温装置）。标准中包括了热切断装置 用于电器和部件的热切断装置，UL 1020。包含新特性、特性、组件、材料或系统的产品，或与本标准要求涵盖的产品不同的产品，以及 涉及火灾、触电或人身伤害风险的，应使用适当的附加组件和最终产品要求进行评估，以: 确定维持本标准意图最初预期的安全水平。一种产品，其特征、特性、组件， 与本标准的具体要求或规定相冲突的材料或系统不得被判定为符合本标准。在适当的情况下，进行修订 应根据制定、修订和实施本标准所采用的方法，提出并采用要求的定义。

Please note: All interim revisions for this edition available at time of your purchase will be included.The requirements for UL 1416 apply to overtemperature protectors, and overcurrent protectors to be employed in radio- and television-type appliances in applications where the protectors are relied upon to limit power, current, or both and where the equipment is to be supplied by a maximum 20 A branch circuit. Compliance with these requirements is not to be regarded as indication that an overcurrent or overtemperature protector would be acceptable in the end-use product.The acceptability of any protector covered by these requirements in any particular component, device, or appliance depends upon the conditions of continued use that prevail in actual service. Accordingly, for a particular application, the protector may be affected by the requirements for the component, device, or appliance in question, and it may be necessary to employ protective devices having features other than or in addition to those specified in these requirements.These requirements do not apply to thermal cutoffs (single-operation meltable-type overtemperature devices). Thermal cutoffs are covered in the Standard for Thermal Cutoffs for Use in Electrical Appliances and Components, UL 1020.A product that contains features, characteristics, components, materials, or systems new or different from those covered by the requirements in this Standard, and that involves a risk of fire, electric shock, or injury to persons shall be evaluated using the appropriate additional component and end-product requirements to determine that the level of safety as originally anticipated by the intent of this Standard is maintained. A product whose features, characteristics, components, materials, or systems conflict with specific requirements or provisions of this Standard shall not be judged to comply with this Standard. Where appropriate, revision of requirements shall be proposed and adopted in conformance with the methods employed for development, revision, and implementation of this Standard.
