Abstract: The invention relates to a compact contactor module (2) for installation in a power post (4). The contactor module (2) comprises a first region (6) associated with a first section (6a) of a printed circuit board (30) said first region (6) comprising control circuitry (8). A power converter (13) provides power to the contactor module (2). A second region (10) is associated with a second section (10a) of the printed circuit board (30). The second region (10) is galvanically isolated from said first region and comprises a 2-pole contactor (12) and an energy meter (16) associated with said contactor (12). A digital isolator (18) transfers signals between the first (6) and the second (10) regions. The printed circuit board is sandwiched between two electromagnetic shield layers (32, 34) made in a conducting material. An enclosure (20) fully encloses above-cited components of said contactor module (2).
