UL 1416 PDF

1 Scope

1.1 These requirements 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.

1.2 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.

1.3 These requirements do not apply to thermal cutoffs (single-operation meltable-type overtemperature devices). Thermal cutoffs are covered in the Standard for Thermal-Links – Requirements and Application Guide, UL 60691.
