UL 1416 – Overcurrent and Overtemperature Protectors for Radio-and Television-Type Appliances

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 wherethe 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 theserequirements 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 usethat prevail in actual service. Accordingly, for a particular application, the protector may be affected by the requirements for the component, device, or appliance inquestion, 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 forThermal 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, andthat involves a risk of fire, electric shock, or injury to persons shall be evaluated using the appropriate additional component and end-product requirements todetermine 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, revisionof requirements shall be proposed and adopted in conformance with the methods employed for development, revision, and implementation of this Standard.
