Circuit Protection Components

Your Partner for Hard-to-find Circuit Protection Components

Circuit protection is defined as the deliberate addition of a ‘weak link’ in an electrical circuit.  This link is deliberately broken in the event of a fault such as high temperature, excessive current, or a short circuit in a conductor to protect the electrical circuit from damage.  Circuits must be protected from electrostatic discharge, inductor flyback, and main supply surges.

If you have ever had a circuit trip in your home’s electrical fuse box, you have experienced circuit protection in action.  There are three general types of circuit protectors:  fuses, thermal circuit breakers, and magnetic circuit breakers.

Circuit protection components include circuit breakers, fuses, GDTs (gas discharge tubes), inrush current limiters, LED protectors, PPTC resettable fuses, surge suppressors, thermal management, thermistors, thyristors, TVS diodes/EDS suppression diodes, and varistors.

VRG Components® can source any electronic parts that are hard to find – in short supply (allocations), end of life, allocated, or have long lead times – especially circuit protection components.  We do this by leveraging our extensive network of carefully vetted, reliable suppliers to provide you with the right circuit protection components to meet your needs.

Our goal is to supply hard-to-find, high-quality electronic components to maximize our customer’s production processes.  With the ability to source components from more than 500 leading manufacturers, we can secure the circuit protection parts required for your project.

Circuit Protection Applications

Circuit protection provides safety and reliability.  It prevents a high fault current from flowing during a fault condition. From a safety perspective, it prevents electrocution and fire hazards.  Circuit protection applications include:

  • Overcurrent Protection – Prevents conductor and component overheating and reduces the severity of Arc-Flash events.
  • Overvoltage Protection
  • Lightning Protection – GDTs (gas discharge tubes), MOVs (metal oxide varistors), protection thyristor devices, TVS diodes
  • ESD Protection – MLVs (multi-layer varistors), silicon protection arrays, polymeric ESD suppressors
