are sealed couplers with locking device that guarantee a safe power
connection in rugged conditions. Among others they are used for on
stage performances and applications in harsh outdoor environment.
Connectors, appliance inlets and outlets exist for 16A, 20A and 32A.
Models of the 16A, 20A and 32A series are shown below.

(a) NAC3MX-W-TOP locking male connector; (b) NAC3FX-W-TOP locking female connector; (c-d) NAC3PX TOP appliance inlet (c) and outlet (d) combination. Rubber, flexible covers for in- and outlet can be added. Separate inlet and outlet units exist also.
Female connector fits in inlet 'c'; male connector in outlet 'd'.
Neutrik PowerCON TRUE1 TOP 16A connectors and appliance in-/outlets fully comply with IEC 60320 standard specifications, which among others means that connection and disconnection under load or live is allowed.
* TOP stands for True Outdoor Protection (IP65).

Female connectors and appliance outlets (image 1d) have four cams (green arrows). The top left cam is wider than the other three. Male connectors and appliance inlets have corresponding notches. The wide cam serves to position a male connector correctly, see image 4; any other position is impossible.
