Description
The Littelfuse FLQ01.5 Time Delay Fuse is a protective electrical component used in control and motor circuits to prevent damage from overcurrent conditions. Rated at 1.5 amps and 500 volts, it uses a time-delay feature that allows brief inrush currents during motor startup while providing protection against sustained overload, or short-circuit conditions in HVAC systems. It is commonly installed in air conditioning heating and refrigeration equipment where controlled circuit protection is required for transformers, compressors, and control boards. Within the electrical system the fuse operates as a safety part that supports current regulation, circuit protection and coordinated equipment operation.
