The bimetal fuses of the 51N and 87N series permanently switch off a load circuit up to 16A at 230VAC. The design offers different connections and mounting options to enable simple assembly adapted to your requirements. After the fuse has tripped, it must be replaced as a whole component. The ceramic body in these series enables response temperatures of up to 270°C. We also offer customer-specific assemblies for these series.Zusatztext-code

Fusible link fuses of the SF/R and SMB series switch off an AC or DC load circuit permanently when the fixed response temperatures are reached. A reset is not possible, so the fuse must be completely replaced after it has been triggered. A back contact is possible if the melting temperatures of the metals act on the fuse due to the subsequent heat effect. Thanks to their compact and small design, these fuses can be installed almost anywhere. We are happy to assemble the fuses according to your specifications. Fuses are final protective elements. We would be happy to advise you on this.Zusatztext-code

The fusible link fuse of the 155.431 series in the open switch construction can switch off a final load circuit of up to 13,5A at 230V. The design, with fastening bracket and plug-in connections, enables simple assembly and connection. Due to the design, clean ambient conditions must be ensured so that the contact system doesn´t get dirty. After the fuse has tripped, it must be replaced as a whole component. The ceramic body enables a release temperature of up to 318°C.Zusatztext-code

Here we introduce you to the temperature protection product group, which can be divided into two classic subgroups. There are fuses in which a fusible link permanently interrupts the power supply when a set temperature is reached. We can also offer you bimetal fuses, which also switch off permanently in the event of an impermissible temperature effect. Fuses can have a very compact size compared to bimetal fuses but are somewhat more sensitive to the holding temperatures. (More on this under FAQ or when consulting our team). Our bimetal fuses offer different connection possibilities and fastening options. Of course, all products can be customized according to your specification.

There are many more possibilities, as we can present here.

Give us a call. We will gladly take time for you.
