Working Mechanism

  • The expulsion fuse holder operates by securing an expulsion fuse that is engineered to break the circuit when a fault occurs by producing a gas that extinguishes the arc. The fuse element melts when a fault is detected, generating gas that expels the arc from the holder and interrupts the circuit.

Standards and Approvals

  • UL
  • CSA

Frequently Asked Questions

What is the difference between expulsion fuses and current limiting fuses?

Expulsion fuses do not restrict the maximum current during a fault, while current-limiting fuses restrict both the energy and maximum current during a fault.

Can Eaton Bussmann Series RBA expulsion fuse holders be used in outdoor applications?

Yes, Eaton Bussmann Series RBA expulsion fuse holders are NEMA-rated and can be used for both outdoor and indoor applications as they are weather-resistant and can withstand harsh environmental conditions.

Is it necessary to replace the expulsion fuse after a fault?

Yes, after a fault, it is crucial to replace the expulsion fuse as it can melt and isolate the circuit during a fault. Neglecting to replace the fuse may lead to an extended outage or harm to electrical equipment.
