Powerlock

Powerlock, also referred to as: power-loc and power-lok, is a single pole electrical connector used by the entertainment industry for high current applications, similar to but considered safer than camlock connectors.Originally developed by Litton Veam in the mid 1990's the Powerlock connector introduced safety features that protected the user against electric shock and making potential fatal connection errors. Such features included finger proof electrical contacts, colour coded insulators, mechanical keys and locking devices.

The original Powerlock is available in 400A and 600A versions, whilst some later compatibles such as "Powersafe" are available at 500Amp and 800Amp. All versions can be used for single phase and, much more commonly, three phase applications. Three phase connections require five separate cables.

The Powerlock style connector can also be used with Sequential Mating Units such. Theses units allow for safe and controlled connection of the single core power cables. These units control the sequence of connection to ensure Earth and Neutral connections are made before phase connections can be made.Thereby ensuring high levels of safety through eliminating connection errors and ensuring safety circuits are always connected.

Applications

Powerlock connectors are typically used to connect to generators. Powerlock inputs are available on many large dimmers and on large power distribution units.
