Eaton’s Industry-first Arrow Hart Color-coded Locking Devices Make it Easier to Identify Circuit Ratings

  • Full locking device offering matches the IEC color standard for voltage rating
  • Simplifies installation and increases productivity

Peachtree City, Ga. -- Power management company Eaton announced a new line of color-coded Arrow Hart locking devices for use in commercial and industrial applications. This industry-first solution brings the six voltage rating colors from the International Electrical Code (IEC) 60309 standard to locking devices, enhancing safety and productivity by making it faster and easier to clearly identify circuit voltage.

“Locking devices, which are available in a wide variety of configurations and voltage ratings, have been on the market for more than 50 years,” said Brian Groenig, product manager, Wiring Devices, Eaton. “Due to the huge variety in products, matching up locking devices in the field is a cumbersome process for our contractors. By adding a small but significant change, we are making these devices far easier to use. Instead of manually double-checking voltage ratings, users can simply match the colors before connecting.”

The color-coded locking devices are available in standard National Electrical Manufacturers’ Association (NEMA) configurations for 20 Amp (A) and 30A applications. Each device type, including the plug, connector, inlet, outlet and receptacle, is produced using the color that corresponds to the correct IEC voltage rating. Color coding provides an ideal solution for buildings with multiple circuit voltage ratings and applications, as well as portable equipment where frequent reconfigurations or setups occur.

The devices also offer the many quality features contractors have counted on in the Arrow Hart line, including an alignment indicator to help orient the plug and connector during installation, robust locking mechanism to instill confidence and enhance safety during use, double dove tail cord grip for superior alignment and clamp force for wire retention, and highly visible and long-lasting circuit ratings printed on the devices.
