Surge Arrester/ Protection

Finmotor surge arrester series was designed to improve equipment protection. Surge arresters are installed near the end of any conductor which is long enough before the conductor lands on its intended electrical component. The purpose is to divert damaging over-voltage transients caused by external (lightning) or internal (switching) events safely to ground. Also called a surge protection device (SPD) or transient voltage surge suppressor (TVSS), they are designed to protect against electrical transients resulting from a lightning flash, not a direct lightning termination, to the conductors.

All models include remote contact, a visual indicator and comply with the UL 1449, IEC 61643-11, and VDE 0675 International Standards.  DIN rail mounting options are available and select models are unpluggable offering the option to replace specific cards as needed.
