A compact profile, nested wire cable isolator includes first and second wire cable spirals, each spiral defining an internal or central region. Each of the spirals has a pair of entrapment members associated therewith. One of each of the first and second pairs of entrapment members is an internal entrapment member, disposed within the internal region of the other spiral. The internal entrapment members are connected one to the other. The other of the first and second pairs of entrapment members are external entrapment members. An energy absorbing restraint includes a first and second anchoring members adapted to connect the restraint to a device, such as a piping system subject to dynamic loads, to a structure. The first anchoring member has the internal entrapment members operably connected thereto. The second anchoring member has the external entrapment members operably connected thereto to isolate the device from the supporting structure.
