UL 248-16:2018 PDF Download

The UL 248-16:2018 standard is applicable to test limiters that are calibrated to specific limits of peak let-through current and clearing I^2t at voltages of 250, 300, 480, or 600 V AC. This standard outlines the requirements and guidelines for the testing and performance evaluation of these test limiters.

The purpose of this standard is to ensure that test limiters meet specific performance criteria and can effectively limit the peak let-through current and clearing I^2t under specified voltage conditions. By adhering to this standard, manufacturers can demonstrate that their test limiters are capable of providing the necessary protection and limiting potential damage or hazards in low-voltage electrical systems.

The UL 248-16:2018 standard establishes the test procedures, performance requirements, and marking specifications for these test limiters. It covers aspects such as dimensions, electrical ratings, temperature limits, and other technical characteristics that are essential to ensure the safe and reliable operation of the test limiters.
