Features

  • Eaton DBU Series expulsion fuses have a weatherproof label for providing rating and manufacturer information.
  • They feature calibrated pure silver element and Nichrome strain wire, making them less prone to premature operation caused by vibration, corona corrosion or ageing of the fuse elements.
  • These expulsion fuses have copper plated end connections for improved conductivity.
  • They are available in voltage ratings of 17 / 27 / 38KV.

Standards and Approvals

  • IEEE

Frequently Asked Questions

How do Eaton DBU Series expulsion fuses break the circuit?

Electrical fuses have a thin piece of wire which melts in case of fault to open the circuit and stop the flow.

What is the difference between MCBs and fuses?

Fuse is a metal piece that melts when there is an excess current due to overload, while a circuit breaker has an internal switch that gets tripped when there is excess current in the circuit.
