Current measuring device for detecting a current in an electric line

A current measuring device for detecting a current in an electric line, comprising:

• a housing;
• a fastening device arranged on the housing and configured to fasten the housing to a supporting rail;
• and
• at least one magnetic field sensor,
• wherein the housing has a first housing part and a second housing part which together form an accommodating device configured to accommodate an electric line between the first and second housing parts,
• wherein the first and second housing parts are separable from one another in order to place an electric line onto the current measuring device and placeable onto one another in order to accommodate the electric line in the accommodating device between the first and second housing parts, and
• wherein the at least one magnetic field sensor is configured to detect a magnetic field on the electric line accommodated in the accommodating device.
