The three pin connector used on the internal power loom of a TK series chiller. A service part for a technician rebuilding a harness, not a mains wall plug.
Anything downstream of the power inlet on a chiller is mains-voltage work. Order this for your refrigeration or electrical technician.
Teco is made in Italy and its spare parts are model-specific — check the model plate on the back of your unit before ordering. See the full Teco range, including the Teco TK aquarium chillers themselves.
