Cautions and warnings
* Do not operate surge arresters in power supply networks, whose maximum operating voltage exceeds the minimum spark-over voltage of the surge arresters.
* Surge arresters may become hot in the event of longer periods of current stress (burn risk). In the event of overload the connectors may fail or the component may be destroyed.
* If the contacts of the surge arresters are defective, current load can cause sparks and loud noises.
* Surge arresters must be handled with care and must not be dropped.
* Do not continue to use damaged surge arresters.
About us
Ampfort’s surge arresters provide fast protection for personnel, equipment and circuitry from high transient voltages and limit resulting dangerous currents. These hermetically sealed gas discharge tubes have precise sparkover voltages and the ability to handle high current surges. We offer a wide variety of GDT’s and it is important that arresters be selected in accordance with the requirements of the particular application. Arresters for special applications are also available and we welcome your inquiries if the model you need is not listed here.
