Surge resistors: protection and safety

An electrical network may accidentally be brought to a voltage higher than its nominal voltage: we then speak of asurge .

Power surges are one of the possible causes of failures in electrical or electronic equipment.

In order to avoid any type of accident, METAL DEPLOYE RESISTOR offers a range of surge resistors or “DC overvoltage resistor” in English.

Filter, discharge & PIR resistors

What are the different types of overvoltage possible?

On an electrical installation, several types of overvoltage are possible:

  • Permanent overvoltage : lasting several hours.
  • Temporary overvoltage : lasting one or more seconds.
  • Operating overvoltage : linked to the operation of a circuit breaker or a disconnector.
  • Lightning surge : due to lightning strike of an electric line.

A wide range of filter resistors

METAL DEPLOYE RESISTOR is at your disposal to define the specific parameters linked to your resistance needs, depending on the market.
