The SOCAY SC30-135 with PTC Resettable Fuses Through Hole RoHS is a self-resetting fuse that offers short circuit protection and long life. It is a two-terminal, 3-amp PTC (positive temperature coefficient) fuse with a standard Through-Hole mounting. Its design features a non-inductive resistor that deploys during a transient event, which causes a rise in temperature and instantaneously melts the interconnects that create the short. Once the short is removed and the current is back in-range, the element automatically re-establishes the conductive path, resuming normal operation. The SC30-135 is compliant with RoHS (Restriction of Hazardous Substances) regulations and is UL, VDE, and CCC certified.
