Description
The Littelfuse SLC045 Time Delay Fuse is a circuit protection component designed for high-current electrical applications in HVAC systems. Rated at 45 amps and 480 volts the fuse uses a time delay response that permits its temporary start-up while interrupting sustained overload or short-circuit conditions during equipment operation. It is commonly installed in commercial heating cooling, and motor-driven assemblies where overcurrent protection is required for compressors, blower motors, and electrical control circuits. Within the electrical system, the fuse operates as a protective safety part that supports current regulation, equipment protection, and coordinated operational performance.
