Littelfuse FLSR300 Time Delay Fuse 300 AMP 600V

The Littelfuse FLSR300 functions as a 300 Amp, 600 Volt Class RK5 time-delay fuse which provides superior overcurrent protection for diverse electrical systems especially those found in HVAC systems. The slo-blo/time lag opening mechanism enables this part to endure short-term overloads before blowing safeguarding motors and transformers during startup. The fuse achieves superior fault current control through its 20 kA interrupting rating. The FLSR300 serves as a protective part in service entrance switches and motor control centers as well as general-purpose circuits. The FLSR300 protects electrical circuits by limiting current while reducing outages and increasing safety features which establishes it as a fundamental element for industrial power distribution.
