High Speed Fuses

High speed fuses are used to protect various semiconductor devices such as IGBTs, GTOs, thyristors, diodes. High speed fuses can offer protection to inverters, inverter drives, AC to DC converters, soft starters, UPS systems. High speed fuses are the best option for semiconductor protection, with the ability to operate in < 1ms unlike the latest circuit breaker technology.

There are 4 main families of High Speed Fuses:

  1. DIN Square Body
  2. BS88
  3. North American
  4. Ferrule (Cylindrical)

The main applications are :

  1. General semiconductor protection
  2. Solar (PV)
  3. Railway Traction
  4. Electric Vehicle (EV)
