Thermomagnetic Protection Technology

The ABB T2L160TMDR63-3P uses a thermomagnetic release mechanism to protect electrical circuits from abnormal operating conditions. The thermal protection function responds to prolonged overload currents, while the magnetic protection function provides rapid response during short-circuit events.

Overload conditions may occur when electrical equipment operates beyond its designed capacity for an extended period. Excessive current generates heat inside conductors and connected devices, which can reduce equipment service life and create safety risks.

The thermal release mechanism continuously monitors current levels and activates the protection function when the overload exceeds the defined operating characteristics. The magnetic release provides fast circuit interruption when a short-circuit fault occurs.
