What are Thermal-magnetic or electronic trip unit?

Thermal-magnetic trip units protect against overcurrents and short-circuits using tried and true techniques. But today, installation optimisation and energy efficiency have become decisive factors and electronic trip units offering more advanced protection functions combined with measurements are better suited to these needs.

Micrologic electronic trip units combine reflex tripping and intelligent operation. Thanks to digital electronics, trip units have become faster as well as more accurate
and reliable. Wide setting ranges make installation upgrades easier. Designed with processing capabilities, Micrologic trip units can provide measurement information
and device operating assistance. With this information, users can avoid or deal more effectively with disturbances and can play a more active role in system operation.
They can manage the installation, anticipate on events and plan any necessary servicing.
