Protecting networks, property and people

The grounding resistor (MALT) controls the maximum current in the event of a leak or insulation fault. 

Strong mastery 

Our design office carefully calculates each application, in compliance with IEEE32-1972 and IEC289 standards (temperature resistance) and EDF recommendations. 

These resistors are crucial to safety, and are installed in unsupervised and sometimes isolated areas. 

A wealth of expertises thousands of resistors in service around the world

Wide range | Modular | Custom-made

from 1A to 2000A

from 380V to 100,000V 

Default from a few seconds to permanent

Hot-dip galvanized sheet metal as standard 

Homopolar resistance

This type of resistor is used for LV transformers and for grounding MV/LV generators or alternators.

Optional:

Current measurement and display
Isolating switch (isolation and connection of several devices to the same resistor)
Control cabinet
Various connections (inside on copper plate, through top or side, plug-in)
Protection class IP00 to IP55
Earthquake resistance
