What is claimed is: 1. A separable loadbreak connector, comprising: a contact tube having an axial passage therethrough; a contact member slidably mounted within the axial passage and movable therein during a fault closure condition; a shock absorbent stop element mounted to the contact tube and limiting movement of the contact member in the fault closure condition, and a piston mounted the passage, wherein the contact member is fixedly mounted to the piston movable therewith, wherein the stop element is positionable to engage the piston in the fault closure condition to thereby limit movement of the contact member, and wherein the stop element comprises a material that deforms when contacted by the contact member during the fault closure condition. 2. The connector of claim 1, wherein at least a portion of the material of the stop element deforms by shearing. 3. The connector of claim 1, wherein the stop element is fabricated from a nonconductive compressible material. 4. The connector of claim 1, further comprising a nonconductive nosepiece attached to the contact tube, wherein the stop element is integrally formed with the nosepiece. 5. The connector of claim 1, further comprising a tubular nosepiece fitted within and secured to an inner surface of the passage of the contact tube, wherein the stop element extends on an end of the nosepiece within the passage. 6. The connector of claim 1, wherein the stop element comprises a tapered end. 7. The connector of claim 1, wherein the stop element comprises a stop ring. 8. The connector of claim 1, wherein the contact member is axially movable within the passage with the assistance of an arc quenching gas during the fault closure condition. 9. The connector of claim 1, wherein at least a portion of the material of the stop element deforms by tearing. 10. The connector of claim 1, wherein at least a portion of the material of the stop element deforms by breaking. 11. The connector of claim 1, wherein at least a portion of the material of the stop element deforms by cracking. 12. The connector of claim 1, wherein at least a portion of the material of the stop element deforms by shattering. 13. The connector of claim 1, wherein at least a portion of the material of the stop element deforms by collapsing. 14. The connector of claim 1, wherein at least a portion of the material of the stop element deforms by compressing. 15. A separable loadbreak connector for making or breaking an energized connection in a power distribution network, comprising: a conductive contact tube having an axial passage therethrough; an elastomeric insulation surrounding the contact tube; a conductive piston disposed within the axial passage and displaceable therein; a female contact member mounted stationary to the piston; and a shock absorbent stop element within the axial passage and restricting displacement of the piston, wherein the stop element comprises a material that deforms when contacted by the female contact member during a fault closure condition. 16. The connector of claim 15, wherein at least a portion of the material of the stop element deforms by at least one of shearing, tearing, breaking, cracking, shattering, collapsing, and compressing. 17. The connector of claim 15, wherein the stop element is fabricated from a nonconductive compressible material. 18. The connector of claim 15, further comprising a nonconductive nosepiece attached to the contact tube, wherein the stop element is integrally formed with the nosepiece. 19. The connector of claim 15, wherein the stop element comprises a tapered end facing the piston. 20. The connector of claim 15, wherein the stop element comprises a stop ring. 21. A separable loadbreak connector to make or break a medium voltage connection with a male contact of a mating connector in a power distribution network, the separable loadbreak connector comprising: a conductive contact tube having an axial passage therethrough; an elastomeric insulation surrounding the contact tube; a conductive piston disposed within the passage and displaceable therein; a loadbreak female contact member mounted stationary to the piston; an arc interrupter adjacent the female contact member and movable therewith; and a nonconductive nosepiece coupled to the contact tube and including an integrally-formed, shock absorbent stop ring at one end thereof, the stop ring placed in a path of the piston limiting movement of the piston relative to the contact tube in a fault closure condition, wherein the stop ring comprises a material that deforms when contacted by the contact member during the fault closure condition. 22. The connector of claim 21, wherein at least a portion of the material of the stop ring deforms by at least one of shearing, tearing, breaking, cracking, shattering, collapsing, and compressing. 23. The connector of claim 21, wherein the nosepiece is fabricated from a compressible material. 24. The connector of claim 21, wherein the stop ring comprises a tapered end facing the piston. 25. A separable loadbreak connector system to make or break an energized connection in a power distribution network, the system comprising: a male connector having a male contact; and a female loadbreak connector comprising: a conductive contact tube having an axial passage therethrough; an elastomeric insulation surrounding the contact tube; a conductive piston disposed within the passage; a loadbreak female contact member mounted stationary to the piston and configured to receive the male contact when the male and female connectors are mated, the female contact member and the piston axially displaceable within the contact passage toward the male contact in a fault closure condition; an arc interrupter adjacent the female contact member and movable therewith; and a shock absorbent stop element configured to absorb impact of the piston during the fault closure condition and substantially prevent displacement of the piston beyond a predetermined distance within the contact tube, wherein the stop element comprises a material that deforms when contacted by the contact member during the fault closure condition. 26.
