Feed overload protection device for connecting feed device to electric load circuit in e.g. multi-family house, has detection unit to determine magnitude of current and reduce current flow in line when exceeding threshold value

摘要

The device (10) has a terminal point (13) electrically and conductively connected with an overcurrent protection device (2) over a connecting line (3). Another terminal point (14) is electrically and conductively connected with a feed device (20) over another connecting line (4). A third terminal point (15) is electrically and conductively connected with a consumption branch (6-1) of an electric load circuit (1) over third connecting line (5). A current detection unit (11) determines current magnitude in the third line and reduces current flow in the second line when exceeding threshold value. An independent claim is also included for a current monitoring arrangement.
