Medium voltage fuses from Mersen cover ratings from 6 A to 450 A. The range holds over 250 products, including ETP fuses at 8.3, 15.5 and 23 kV, capacitor fuses and back-up fuses up to 24 kV. Stoklink ships worldwide from Turkey on EXW terms, and quotes for project volumes are available on request.
What's in this range
- ETP fuses at 8.3 kV, 15.5 kV and 23 kV.
- Amp-Trap medium voltage capacitor fuses from 1.0 kV to 5.5 kV.
- 5.5 kV ferrule mount transformer fuses.
- Limitor NF/UTE back-up fuses, 7.2 kV to 24 kV, type FR.
How to choose
- System voltage: the fuse voltage rating must match or exceed the network voltage.
- Application: transformer, capacitor or motor circuit, each uses a different fuse characteristic.
- Current rating and time-current curve: coordinate with the upstream relay.
- Interrupting rating: it must exceed the available fault current.
- Dimensions and end fittings: the fuse must fit the holder or switchgear mounting.
FAQ
What is a back-up fuse?
A back-up fuse clears high fault currents and is paired with another device, such as a switch or contactor, that handles low overcurrents.
Why are capacitor banks fused separately?
A failed capacitor element can release stored energy. Dedicated capacitor fuses isolate the failing unit and protect the bank.
Can I request fuses for switchgear projects?
Yes. Availability varies, so request a quote. Stoklink ships worldwide from Turkey on EXW terms.
