Additional Details

The TR4-1/2R is designed with a time-delay characteristic that allows it to withstand temporary overloads without interrupting the circuit. This is particularly useful in applications with motors, transformers, and other inductive loads that draw high inrush currents during startup. The fuse has a specific interrupting rating, which indicates the maximum fault current that it can safely interrupt. It also has a voltage rating, which indicates the maximum voltage that it can handle. The current rating indicates the amount of current that the fuse can carry continuously without blowing. The TR4-1/2R is UL Listed and CSA Certified, ensuring that it meets safety standards. It is also RoHS compliant, ensuring that it meets environmental regulations. Detailed specifications, including the time-current characteristic curve, interrupting rating, voltage rating, and current rating, can be found in the Mersen datasheet for this part number.
