Siemens Varistor with LED – Protective Component with Status Indicator
The Siemens Varistor with LED is an electronic component designed as a sand-filled fuse. Despite the name 'varistor', the technical data classifies it as a fuse with an integrated LED for operational status indication. It is suitable for AC voltages from 24 to 48 V and DC voltages from 12 to 24 V.
The LED instantly shows if the fuse is intact – no multimeter required.
The wide voltage range AC 24–48 V / DC 12–24 V makes the component versatile.
The sand filling reliably extinguishes the arc, enhancing safety.
The rated current range from 0.1 to 5 A covers many electrical installation applications.
The component combines the functionality of a fuse with the optical indication of an LED. This eliminates time-consuming troubleshooting as the status is visible at a glance. The compact design allows use in tight switch cabinets and distribution boxes.
Ideal for electricians and installers
This component is especially suited for professional electricians and building technicians who require reliable and maintenance-friendly installations. It is also a dependable solution in industrial controls and home distribution boards.
How to use the Siemens Varistor with LED
Install the component in a suitable fuse holder with the corresponding rated voltage. Observe the permissible voltage (AC 24–48 V / DC 12–24 V) and rated current (0.1–5 A). Installation follows standard rules for fuses. The LED indicates the operating status after power-up.
Siemens is a global technology leader focused on electrification, automation, and digitalization. Its products are known for high quality, reliability, and innovation – whether in building technology or industrial applications.
A Varistor with LED is an electronic component designed as a fuse with an integrated light-emitting diode for status indication. It protects electrical circuits from overcurrent and overload.
The component is designed for AC voltages from 24 to 48 volts and DC voltages from 12 to 24 volts. Exact values are printed on the housing and in the technical documentation.
Install it in a suitable fuse holder of the corresponding size. Ensure that the rated voltage and rated current (0.1–5 A) are not exceeded. The LED indicates the operating status after power-up.
The integrated LED signals whether the fuse is intact or has blown. When the fuse is intact, the LED lights up; when blown, it turns off or changes color (depending on the model).
The name 'varistor' refers to the original designation as a voltage-dependent resistor, while the technical classification corresponds to a sand-filled fuse. The component functionally combines both properties.
