Hi ,
Happy new year.
Small typo in this document : https://documentation.meraki.com/IoT/MT_-_Sensors/Product_Information/MT_Overviews_and_Datasheets/MT...
Does MT40 have surge protection?
No. MT40 is strictly a power monitor and controller. This unit is not intended to be used as a surge protector. Uusing a surge protector or a power conditioner upstream of the MT40 is recommended.
