High quality SIBA / ESKA ceramic time delay microwave fuses in various values and lengths. Different pack sizes are also offered. Choose the current rating in Amps and length in mm that you require. Also choose from multiples of 1, 2, 4 or 10 fuses.
The fuses supplied are the two most common sizes fitted, 20mm and 32mm in length. Obviously we do recommend that you measure the length of your old fuse before ordering but for easy identification the 20mm fuses are a little smaller in length than the diameter of a One Pound or One Euro Coin. The 32mm fuse is about 10mm longer in length than the diameter of the same coins.
The fuses are easily identified by looking at the silver end cap of your old fuse. The current value will be shown as T10A for a 10A fuse. Other nomenclatures shown on the fuse cap may be AH or S. The fuses offered here replace them as well.
- 20mm Length x 5mm Diameter
- 32mm Length x 6.3mm Diameter
It is important to check your old fuse before ordering as the different sizes are not compatible with each other, they will not fit in the fuse holder.
The fuses can also be used in any other application where a time lag fuse is required such as a power supply.
Sometimes the subject of the fuse rated voltage comes up as the fuses supplied may have a 500V rating on them. Generally, the line or mains voltage in Europe is 240V AC so the difference does cause confusion.
The crucial specification of a fuse is the current rating as this is the rated current flow, which if exceeded, will cause the fuse to rupture and break the circuit.
The voltage rating of a fuse is the maximum voltage that can be applied across the end caps without a sustained arc forming inside the fuse. The maximum voltage that can be applied in Europe is 240V so the fuse must have this minimum rating. If the fuse voltage rating is higher the fuse rupture will be quicker and cleaner with no internal arc forming.
In essence a fuse with a voltage rating higher than 240V is a better option as the break is cleaner and quicker and the fuse will not catch fire internally. In the event of a genuine fault a quicker cleaner break can prevent damage to other parts of your oven or appliance.
