'Powercon' offers 20 amp rating in a secure-locking, compact housing, and meets all current safety standards. The series offers a 3-pole connection, with pre-mating earth connection and compact design (the series shares many body components with the 'Speakon' twist-lock loudspeaker connector, though naturally is totally incompatible!). The secure Neutrik strain-relief chuck cable strain relief accepts cables 5-15mm diameter, and the locking is by the twistlock principle with metal latch (as on current 'Speakon' connectors).

Cable connectors have screw terminals (max. wire size 4mm), panel connectors have 'Faston' 4.8 ×0.5mm 'spade' terminals. NAC3MP panel connectors have plain mounting holes and are airtight. The -WOT variants are without the terminal barrier, for use with larger insulated spade terminal receptacles.

The series has two variants, the A (inlet) and B (outlet) types. Both are similar but have different keying to prevent mismating and are different colours. This means it is impossible to produce a short circuit with correctly wired connectors.

Type A is for power inlet, and is colour coded blue (equivalent in function to IEC320 cable female and panel male). Type B is for power outlet and is colour coded grey (equivalent in function to IEC320 panel female and cable male).
