Problem & Solution
In stage lighting and high-density LED screen deployments, standard friction-fit AC power plugs (like IEC or standard utility connectors) risk pulling loose under cable strain, movement, or stage vibration, causing immediate operational disruptions.
This 20A 250V Powercon-style connector series solves connection vulnerability by implementing a tactile twist-lock mechanism. The spring-loaded locking catch ensures continuous electrical contact for stage lights and visual displays, preventing accidental power line drops during operation.
Who Is It For?
This product target includes AV technicians, stage lighting riggers, LED display wall installers, and event infrastructure crews building or replacing locking AC power links. It is designed for buyers who need custom-length power cabling with standardized key-coded connectors.
Key Features
- 20A / 250V AC Electrical CapacityDesigned to manage higher amperage draws required by high-output stage fixtures and modular LED screen power chains.
- Quick Twist-Lock LatchMechanically locks into matching chassis sockets, preventing dislodgements caused by cable tension or physical vibration.
- Keyed NAC3 Color Coding (Blue/Grey)NAC3FCA (Blue) and NAC3FCB (Grey) feature unique physical keyways to prevent accidental intermating of power input and power output lines.
- NAC3MPA Chassis Socket OptionAllows custom mounting onto distribution racks, equipment enclosures, or custom patch panels.
- Internal Strain Relief ClampGrips the outer cable jacket internally to protect wire solder/screw points from direct pull force.

FAQ
NAC3FCA is the blue power-in cable plug, while NAC3FCB is the grey power-out cable connector. They feature distinct mechanical keying so that power-in lines cannot be plugged into power-out sockets.
It is primarily used for power feed connections on LED display screen cabinets, automated stage lighting fixtures, power distribution distros, and modular equipment racks.
No, this is a standalone connector head/socket unit that must be attached manually to your custom-cut multi-core power cabling.
Standard Powercon NAC3 type connectors are designed as non-breaking capacity lockable connectors; circuit loads should generally be switched off at the breaker prior to connecting or disconnecting.
Final Verdict
A practical power connector system for stage lights and LED display installations where cable lock security is essential. With 20A 250V capability and clear keying separation between NAC3FCA and NAC3FCB types, it offers functional reliability provided you have basic cable assembly skills.
