Assembly (1) with an energy absorber (2) for absorbing energy in the event of an overload in order to reduce the resulting load on an object coupled with the assembly (1), so that overloading of the object is avoided by the energy absorption of the energy absorber (2) when the overload event occurs. The energy absorber (2) comprises a fastening device (3) thereon and a holding device (4) provided on the energy absorber (2), wherein the energy absorber (2) is provided to absorb energy when there is a relative movement between the fastening device (3) and the holding device (4). The energy absorber (2) comprises an absorber cylinder (5) and a piston device (6) with an absorber piston (7) and a piston rod (8) connected to same. The absorber piston (7) defines a first chamber (10) of an absorber chamber (9) on the absorber cylinder (5), being filled with a field-sensitive absorber fluid (12). The piston device (6) has an absorber valve (13) with an absorber channel (14) which extends in an axial direction, which absorber channel (14) can be exposed to a field (15) of the field generating device (16). The ratio of the outer diameter (18) of the piston rod (8) to an outer diameter (17) of the absorber piston (7) is larger than 0.6 and the first chamber (10) filled with the field-sensitive absorber fluid (12) extends in a space (28) around the piston rod (8) so that the field-sensitive absorber fluid (12) is pressed through the dampening channel of the absorber piston (7) when there is relative movement of the fastening device (3) and the holding device (4) of the energy absorber (2) during energy absorption during the overload event.
